Just a thought about Ekko and his E
I havent had a chance to play against him since the PBE, but me and my friend just spent an hour or 2 messing around in a custom game and something really stood out to me.
The first part of his E. It is capable of clearing just about every wall in the entire game that can be jumped. It is almost like it is being treated as a teleport rather than a dash. For those that dont know, teleports only need to get halfway through a terrain to clear it, dashes need the whole distance.
It feels even more mobile than Lucians E, which has 100 more range that it.
If anything should be changed, i think that should be the first step.
EDIT: Wonderful discussion. So glad people downvoting could bother to post their thoughts on the range of his E.
