I think you have mistaken "rush" with "rush impact". Rush has no stun effect and does no dmg. It is simply gap closer. No, its basically the same thing. Destro with hammer crush + rush. In 2.0 it will be worse, since they get mass fear. Its going to be the same clown fiesta. With the addition of rush, you're removing the biggest weakness of a destro. Their mobility. With the addition of 2.0 skills, and olympia balance, its just too crazy. You can compliment on their strengths, such as 2 / 3 / 4. But adding a completely new mechanic to the game, is insane. It is insanely hard to CC a destro. You really want a cat buffed / frenzy / zealot / rage / un-nerfed VR / rushed / party UDd destro killing everyone in 2.0? The only counter play is to kite him, if he has rush. You remove that counterplay, and the game becomes unfun. You might as well add cancel sticks while you're at it.
