slow: I thought about adding CC, but wasn't too sure whether that would make him too strong as a fighter...but then...Darius, Diana... :) I think about adding a slow to the W-toggle => "Frozen Mallet effect". Thanks, for the suggestion, Braumissomanly.

Riots think that permaslow is, in general, bad for gameplay(hey, they are planing to remove frozen mallet soon), so move bonus ad to passive(from W) and make some active CC skill will be batter IMHO.

Something like "active - shoot a lightning/mana bolt/whatever at target enemy, dealing X+%AD damage(like 220+60% bonus AD at max rank) and root target for 0.1 sec, then slow for 90%, decaing to 0 during the 3 sec duration.

Every melee champ NEED mobility or ranged CC(or insane tankyness) to be relevant or he will never. never be able to do.. well, anything. Every ADC know how to kite now...
