I now understand the bans

I'm a potato bracket player, barely ever played this hero and then just started spamming when seeing that everyone is banning him in the group stages.

I soon realised the blue dude is broken. Feels better however than playing sniper or troll seeing as there is at least some skill involved in positioning and the euls stun combo. Anyone else played more of him recently? What the hell is making him so imba? My guess it's the good laning ability combined with the fact that he scales really well throughout the whole game. Lacks armor though when playing against right clickers.
