Morgana's abilities are great. I love to play her. On the other hand, there have been plenty of games where I wish they had a Morgana instead of the Lux that is destroying us.

Her full-team multi shield is godly, as is her two target snare and her aoe slow. She doesn't do Morgana's damage, but Morgana's damage was never good enough to take a hero from 100 to 0 because of the delayed action ultimate and lack of fourth damage ability.

Basically, it's like this: A team with a very strong melee AD carry (Tryndamere for example) will benefit hugely from Morgana. So much so that people ban her out of fear of an AD carry + Morganna.

On the other hand, a tanky team with lots of CC on their side and a ranged AD carry would benefit more from Lux.

Team of Malphite, Alistar, Janna, Lux and Caitlyn will destroy you because of the heavy CC. Unless you have Tryndamere+Morganna on your team

Lux is a better "disabler" she can lock down 2 champions at a time and has a AOE slow, and her shield isn't unwanted but only really helps if she is going AP. Support OR AP lux can be silly with her ult, and its low cooldown.

Morgana is the better "support" when put into a premade she can keep fiddles, kait, nunu, and ANY assasin from being CCed. Morgs Ult makes people scatter and can do some pretty heavy damage if you are AP built, but it requires team coordination to make good use of it and has a long cooldown.

Basically, Lux is a Pub stomper while morg is a team player, no matter how you play them. Lux (imo) takes more skill to do DAMAGE but morg takes more skill (or atleast knowledge of the game) to be effective [as a team]

Lux... Crazy high mana costs like Morg with lower CDs is a recipe for running OOM in 2 seconds flat, especially early game. She *Can* farm, but only if no one tries to harass her at all, her skill shots are fairly dodgeable, even the laser unless they come out of the bushes when you don't expect them. She can poke from an uber long range, sure, but only like 3-4 times before she is OOM and can't execute a combo, and her pokes are pretty weak unless you use you passive and autoattack in combos with your skills for damage, which completely nullifies her range advantage. (You have to get inside horrible instant rape radius to aa with Lux.) Lastly, even the little bits here and there of damage Lux can take from minions do not just heal off like what Morgana's passive does for her.

I have heard someone say that Lux was "Morgana 2.0", but having bought Morgana as my first champ when I started the game (I hated her and went levels 5-25 maining Soraka) and having bought Lux and tried to play her because she looked like fun... I just don't like to play Lux, no matter how careful I am (no utilizing the passive) or how aggressive I am (combo hell) or what lane I take, I end up running out of mana instantly and out of health not long thereafter. I have had a few lucky games where I managed to get fed as Lux, and honestly, while she can blow up a champion here and there, and her ulti can do some really **** annoying damage fairly often, the only thing she can really do is halt mid pushes cold by making the enemy team feel like she feels all the time (running out of mana and health... I need to go back to base ><) and if she doesn't get fed... the game just goes downhill from there. You might snipe a kill or two that other teammates did most of the work for, and you might save someone with a well timed snare and/or slow, but that's about it. I proclaim Morgana Lux 2.0 preemptively (before Lux came to the league, Morgana was better).

Edit: Oh, also, all of Lux's cast animations are way too **** long. You have to stop for .5 seconds or more just to throw that snare that has a 50% chance of being dodged even if you aimed correctly backward while running away or chasing... yeah, just doesn't cut it, and while Lux's Lucent Singularity has a slow component... it has travel time to get to the location it was shot to before it gets set up, the only situation where you can force enemy champions to run through it is when you are defending a turret (nearly always the second mid turret), and even then the enemy can just wait till it goes down and then charge while it is on CD again. Lucent never helped me escape or catch anyone, that's for sure, because in the time you are casting it and firing it to the target either your chaser is beating on you while you stop to fire or your runner is getting farther away while you stop and is probably going to leave the range of the slow before it gets there.

Lux's abilities are comboable with autoattacks but... the cast animations and travel times and autoattack speeds and skill cooldowns just do not synchronize well with each other, add in the skillshot factor and finding an enemy out of position and then proceeding to land a full combo on them will be incredibly difficult... if you manage it you better be sure they will be prepared to dodge the laser if they have ever seen Lux before.

Lux has mana issues, long cooldowns and never quite makes it there as a burst caster or a support (That shield is hard to land)

That being said I love Lux to death. Most fun I have playing this game.

Now? Morganna.
If you asked me 3 months ago I'd say Lux.

This isn't even a fair fight. Lux is borderline useless compared to Morgana.

As some1 who has mained Lux for some time, I have to say, Morgana is the better choice right now. Much easier to play and as effective as a good Lux when played decently well. The notable exception is that Morgana is a common pick/ban in ranked where as Lux is rarely ever banned (and an uncommon pick). I will add that very few people I see play Lux actually build her in the ideal manner or play her particularly well. (My preferred build on Lux is Morello's Evil Tome, Sorcerer's Shoes, Lich Bane, Rabadan's Deathcap, and situational AP items, Mejai's after Morello's+boots is an option if you/your team is doing reasonably well).

They need to make Lux ult global slightly better late game scaling.

the only thing that i hate with lux against morgana right now is that lux's abilities have a delay to them. lux has to stop to cast her shield and even after there's a cast/travel time that could mean the difference between saving an ally or being too late. so morgana with her insta shield that blocks CC gives her the edge in support, but lux has better range and a more aggressive passive than morgana's sustain passive giving lux the edge in AP carry/nuke/whatever

so played as a support: morgana wins
as an AP pokey pokey: lux wins
