hey SilentSide thanks for the review! you definitely pointed some things out. let me explain some thoughts, then i can look at some changes.
Pantheon is a AD caster/assassin, and Legion is an ad ranged carry. so where pantheon has great scaling abilities with moderate cooldowns, legion has mostly stat steroids. i was going more with versatility then indomitable, as carries should be naturally squishy to balance high damage output. i am hardly the first person to quote the bible, it makes for great fiction. its easily one of the best stories of all time, and as a source is generally well known.
the passive is super strong yes, its a lot like trynds crit passive or ashes, where it makes auto attacking his premier source of damage. since his Q is stance he can proc it whenever he wants the cool down starts once its activated, so since all his spells are non target spells, he can spam out all abilities in a second to proc passive in a fight, however, i feel that the spells have a very natural progression, you poke with a spear through, reducing armour, when enemies get closer/think about attacking back, you proc the Q, use your attack speed buff and fire away, remember he is ranged, and during the rest of the fight, passive is running. the two options would be spammable abilities to keep it going on and off, or situational abilities with long cool downs so that his passive can run solid for an entire fight.
in his lore he is supposed to come across as a collective group of soldiers who have sworn to keep fighting, if that didnt come across as the main theme, thats my bad.
Q - this is not a self root, but a duration effect, all you need to do is stop moving when they reach you...already i can see the confusion....this is a good opportunity to maybe change the spell to proc as long as you are facing the enemy. in fact i will almost certainly do that. its true that anyone with range could ignore this ability, however since he is ranged, he would attack back. also it is useful in bushes and perhaps ganking lanes where enemies would have to go wide around you to avoid it. a gap closer would probly be ineffective with a ranged carry. even with his passive short ranged AS.
W - mostly this is for fighting tanks or melee dps that want to close the gap, instead of other carries having escapes legion has a as boost that might allow him to go toe to toe. the active is another carry ability to make attack damage items stronger.
E - admittedly he could benefit from an Aoe, but his farming would be perfectly fine already, and as it stands, instead of Aoe castable abilities, Legion is a carry, and gets stat buffs instead. I dont want any more cc then the avoidable Q i think this would be too strong. it would be up to Legions team to provide cc for him...imagine master yi or trynd had a ranged stun....yes pantheon does, but he is a caster.
at this point with castable armour pen debuff, and attack speed steroid, and bonus crit chance, i feel legion is prepared to begin a fight with other champions. if that champion happens to be melee, then Legion benefits from a knock up/slow combo as well as additional AS.
R - I went with the stealth for a few reasons,
1 allows positioning in game - very important for carries
2 juking possiblities, as ranged carry his low Hp pool is vulnerable, so a well timed ult can allow him to juke a bit near brush or corners.
3as an undead soldier inhabited by thousands of ghosts, i thought it would go good with the lore if he could use them somehow example ghosts covering for him attacking with him.
as i see it, it stands -
1. pantheon is melee, AD caster/assassin, Legion is ranged, AD carry - but yes they both have spears
2. i feel the stat buffs are natural for a carry. the q would be fun to use most characters have a poke for laning
3.as far as lore....being a dead legionnaire harboring more dead legionnaires, he has legionnaire weapons, uses legionnaire abilities, and as ult calls upon said legionnaires for aid.
your review was very helpful in pointing out Legions weaknesses, here are my initial thoughts,
Passive - make it easier to be up
Q - instead of stationary - facing enemies, now can be used as a sort of charge (although he is very slow)
W - attack speed buff will stay, its his main carry ability
E - this was an idea before - Legion throws a pilum at target location, hits enemy for damage and armour pen, think J4 but single target, longer range. Upon casting legions ghost companions add their pilums to the throw hitting an area around Legions (slight delay) doing light damage possible slight slow
R - ive been meaning to simplify, some ideas are throw away stat buffs, and go with ghosts that charge attackers while he stealths briefly, more levels more ghosts. they cannot crit, but do land one attack unless they are targeted on route. Legion can continue to attack this way adding damage, or slink off to new position. thanks for the review!!
