And the Evo of pekka is ranked the second worst evo by pro players.
The usage ratea of pekka and evo pekka is one of the lowest in top ranked.
The card is severly underperforming and weak. Plus it always does not get to land the final hit when it reaches a troop or a tower whether on offence or defence.
Years ago pekka recieved a change of a range buff combined with an hp nerf. And the month after that, pekka recieved a nerf to the given range buff but did not regain the lost hp. Since that time pekka always was bad.
