Crit Death Dance GP died?

i am the main and creat the death dance build( + + + + + ),after i see the changes on his keg(e) i just test this build again in normal game,and i match up with another gp.But after the game i spotted that before the change,this build is better than armor pen build in teamfight.In this game,even the late game this build's teamfight potential is worse than armor pen GP now.Riot,you know gp's problem is he gain too much damage from his powder keg with armor pen build,i know you want to nerf he early game let he can be punished by others.But now you are totally Destorying the build which i find,I don't think this is fair for me since i can wreack the armor pen gp before but now,even my technique is better than him but i still lose in teamfight and 1v1 fight.You are destorying my mains riot
