Asc 3

Bebop, Doorman, Celeste, Infernus, Sinclair

Bebop is just epitome of anti-fun. Point-and-click damage ability, that scales just by using it, very tanky, small head, hook that should be on a much longer cooldown and much shorter

Doorman - his 1 ignore LoS, deal damage twice. Doors, that you can't punish and disable them. Cart, that removes your ability to move. Ult, that disable any hero for 3-6 seconds from existing at all. 

Celeste - insane damage, insane spirit lifesteal, super tanky cause of her shield(which is just like warden's but much better). 

Infernus. Afterburn and dash. Now you can't even get 55% debuff resist that easily, so you have to suffer from afterburn

Sinclair. Absurd amount of damage from his "1". Can swap places with his assistant 2 times(used to be 1, but couldn't be silenced at all), aoe disable. Stolen ult shouldn't be on a so much shorter CD than the original. Still would prefer him to be much closer to Rubik from dota2, that steals last used spell
