This is basically a list of heroes or a specific build path for a hero that are so bad that picking them just handicapes your team into a 4v5.
Alpha: Poor hero design, only possible play style is to full engage. Was strong when aftershock was broken but Alpha is useless now.
Baron: Was always easy to exploit due to very weak early game but had scary late game. Now Baron’s late game is just as weak as early game making laughing stock.
Fortress: Overloaded kit so Semc had to resort to nerfing stats down to the ground making him garbage.
Cp Joule: Was strong due to overpowered ultimate, ultimate got nerfed to the ground making cp Joule straigh garbage.
Kensei: Broken kit so he got the fortress treatment.
Cp Kestrel: No damage.
Koshka: Hero itself is alright but terrible meta for her.
Krul: Same issue as Koshka.
Ozo: Poor hero design, useless ultimate, gets fucked by any form of cc, spellfire and shiv are basically built in every game.
Rona: Ozo 2.0
Petal: Wp build too weak, Cp path terrible by design for 5v5.
Cp Silvernail: No damage.
Cp Skye: Bad by design for 5v5, hero was cleary designed to win 1v1s in the 3v3 jungle. She also needs like 3 items to start dealing damage on top of that.
Taka: Hero is in general too weak and the current meta makes the matter even worse for him.
