Earlier today Riot released this video which previewed the new champion Ekko.
As you can see in both the video and the pictures over at http://Surrenderat20.net Ekko seems to have a lot of time based abilities, but acts like a melee attacker.
Went on the PBE public chat and talked about it with a bunch of people and we came up with some theories with what exactly he will do.
A lot of people believe Ekko will have an ability that allows you to rewind time in an area around him or in a target area. This area rewinds all cooldowns, health, mana, energy, etc of both enemies and allies.
However I don't think this is a possibility. Riot has previously stated on the Rek'Sai knockup topic that any kind of sudden changes to a character's control is not something they would like to do. To me he looks like a hit-and-run assassin similar to [Tracer from Blizzard's new Overwatch](http://us.battle.net/overwatch/en/heroes/tracer/).
He will probably have at least two offensive abilities but be largely AD focused, then have an ability that takes him back in time. So he could run in, do damage to the enemy carry then zoom back in time. But according to the video, his time ability will not reduce any damage taken or undo energy/mana used. Finally, it looks like he sets his current state which allows him to travel back to only that spot.
So these are my thoughts. I'm super hyped about the new guy and can't wait to test him out. What do you all think?
P.S. If the pictures don't work I officially hate the boards and will attempt to fix them for 10 minutes before giving up.
EDIT1: Pics don't work. Joy.
