It's not the same. CS/SR's AOE KB has a limited range and you can't pinpoint the location of your target. On the other hand, BH/TR's pull can be planned an has a "very very" long range compared to CS/SR's AOE KB. Also one of them is an offensive ability while the other one is defensive.
I'm not talking about the acid-pool. That's so last week. Nowadays, BH/TR's are pulling to fire which is insta-kill.
Please stop trolling. Your AOE KB is not planned in advance and there are ways to counter it. It has limited range. Also I'm considering the fact that you're not really a CS/SR after defending this pull ability this much.
