grimspike should have knockback on his inferno

[AlinBallin]

took me 40min to kill it on $ player 5. at lvl 20 as a barbarian and i honestly think thats what makes this boss challenging. his knockback

My baba's helm/armor/belt was destroyed in few seconds today on player1... But i think knockback should be still on this inferno. Only thing that should be changed in GrimSpike is his behavior (but i suppose it's just to much work). What i'm talking about? He still just cast. He just should engage melee combat too, as other mobs of his appearence type. Cast + approach + melee + cast + melee etc. This would let melee heroes be close to him to attack but still suffer knockback, fire dmg etc

He is still challanging on later difficulties. That no knockback on infenro is temporary change. Grimspike AI script could be changed into something more fitting later on.
