Now y'all can stop bitching about ekko being op...
Gypsylord (NA) - about 7 hours ago So first of all, giving his ult a mana cost is not likely to solve any of the frustration problems it might have. In the vast majority of fights it's going to be used the same way, under the same contexts. If the spell needs a downside (not saying it does) giving it a mana cost isn't going to solve that.
That said, from a design standpoint I do agree that there is something to the idea of "he's been spamming spells and is out of mana, now is my chance to strike." His ult not having a cost directly avoids the minor gameplay idea of "characters are weak when they're OOM." My bad on that one. We'll be fixing it for 5.12 by upping the cost to 100 (from 0). There were localization things that prevented it getting in for 5.11.
As a side note, adding higher mana costs across Ekko's kit (we're also upping W cost to 50 from 30 in 5.11) helps mitigate burst in an indirect manner. Higher costs means he has a harder time farming and may want to invest in more mana/regen itemization. More gold spent on mana + less gold overall = lower AP totals at X point in the game.
