I got into a discussion with CertainlyT about this concept.

Is there a champion in the works planned to be a 'Pure' Jungler, like Skarner or Nocturne?

Funny, a year ago I had an idea for a time assassin ultimate

It would be a toggle or held skill with like 100 charges, like statikk shiv but with a different recharge mechanic, and when toggled/held it would just increase your movespeed by a ridiculous amount and leave a flame trail behind you while depleting charges rapdily. Obviously, it would be unusable without charges.

The idea would be that he was sped up through time and he could both move insanely fast and the friction created from his speed would set the area ablaze.

To give an idea of how fast, he could travel from mid to top in about 1 second while toggled on

Of course, "trail behind you" doesn't really scream assassin, so either change that or put something on his kit that gets people to stand on it.

It would probably recharge at like, 1 unit a second and grant a bonus on kill. Maybe like 20. And ideally, charges would only be depleted while he was actually moving.

This ult would give him really insane mobility, giving him unprecedented teamfight/lane mobility and close to TF/Panth kind of global-esque ness. Of course, to compensate for this he'd have to be highly skill based, not giving him any innate defenses and forcing you to rely on mobility.

Of course, you could make this kit a lot more vanilla by giving him a "rewind" un-gap closer like reactivating leblanc's W and make his ult just a targeted global/semi-global thing. This would probably work better, I just think my idea is cool.

Ezreal, can we ever expect to see another melee carry? In the over 3 years LoL has been out we've only ever got one other one (Fiora), and all melee carry viable is highly questionable--not only this, it's the most ignored class in the game (only 3 characters total; GP got morphed into a fighter long ago), and they're all the most homogenous group in the game; they all have sustain, an AD steroid, gap closer, survivability steroid, and an MS/AS steroid (tryn has an AoE slow and crit chance instead), and some form of low to moderate AoE damage---additionally, all 3 are sword users.

Are we doing to have to wait another 3 years to get a melee carry or wait until another major game overhaul for melee carries to be viable or should melee carry enthusiasts just move on?

Most likely a Passive/Active ability would feel the best. You want to make this shield feel like protecting you so having passive mitigation is a given. Now, you want to move it to create angles against certain plays while opening other sides for counterplay. Making the shield move randomly around you feels horrible as with all random mechanics so the active part is a given too.
Now, mitigation is always weird when it comes to balancing. It's either strong early and weak late if it only migrates flat numbers or a flat percentage or too strong if you make it scale (See: Poppy). I wish you best of luck finding the sweet spot there when balancing but I'd say having a flat value mitigation with a scaling component like current mana in the reverse direction of Poppy would work the best - Ex: You have a base mitigation of 80 + 0,25% of your ap but the lower your mana get's, the weaker the shield get's. It would open up counterplay since the enemy had a valuable way to weaken your shield: Dodging your skills and bringing you oom.
When it comes to the active, it should feel like a clutch escape. The cd should be fairly long to make you think about the usage and the shield shouldn't travel instantly but with a slight delay. As an extra goodie there are several ways to make that active feel good besides the 'oh I mitigated some damage by moving my shield'-part. It can block skillshots when active, it can double the given mitigation - you name it. I'd also vote for the shield to be fixed again after activation due to: Being hit by an enemy attack, pressing the button again and/or exceeding a certain timeframe to create strategy and counterplay - Ex: Shoot a skillshot to the right so the enemy has to adjust his shield against it. Voilá you created an opening at the left side of your enemy which you can use within the cd timeframe.

Just...throwing in ideas, you know :3 Keep up the good work Ez. I still love you for creating Vlad <3

Hey Ezreal, I'm going to start of by saying Final Fantasy is my favorite set of games ever. On this note, consider the Red Mage: useful in offensive magic, defensive magic, and swordsmanship; but a master of none. Now consider the recent new unique passive "Spellblade" and see where I am going with this. A melee champion with an AD and AP ratio kit (not on the same skills) that relies on using spell effects modifying his auto to sustain in lane and deal damage. And I'm not talking about Yorick.

Vayne definitely gets the feel of not having any particular homeland. As a player, I don't feel like this detracts from her background, as she's more of just a night hunter is just awesome. She's obviously not noxian, but if she identified as demacian in a quote it would feel forced.

So I think she's okay.

did i just go back in time!? ZILEAN HOW DARE YOU

Angus is coming, prepare your grills

Ezreal, will we ever get a voodoo, shaman, or witch doctor inspired champion?
Witch Doctor from Diablo 2 and DOTA 2 are some of my favorite classes/heroes I've ever played.

Any chance for some AP Ez loving in the coming... decade...?
