Difference between Ekko's dash and vayne's tumble
Ekko's E is 325 units while vayne is 300, only difference is 25 units. But why can ekko pretty much jump every wall while vayne can barely tumble through any wall. their dash is also an aa enhancer and has low cd Ekko e at lvl 5 is 7 secs with 25% cdr its 5 secs, with 40% its 4 secs. vayne's tumble has a 2 sec cd at lvl 5
Tl;dr Ekko and vayne's dashes have almost identical dashes but ekko can go through walls.
