It's funny that people bitch about removing dispel from monk/druid/shaman like that would DESTROY their class. You know, there were 2 expansions full of arena seasons where you had no dispel and you were viable nonetheless. And yo, mages had deep poly back then too. Even blanket/poly. Or if they were fast nova/poly.
(Yes, druids could shift out of polys, but this is a shaman thread overall, and shamans were viable too. More than viable with comps like MLS etc.
During the 2 expac, mages didn't have a crazy mobility, a huge tankiness, a enormous instant burst, while being able to blink for no reasons and water elemental was a burst cd or was used to cast deep freeze on the healer, and a extremly visible Blizzard favoritism for them.
Of course not having a magic dispel is this case wasn't so bad because your actions against (Kick them, training them : phd used to be a nightmare for mage, same against any prot warrior teams) them was effective compared to know.
If they change classes to be like that, yes, you can remove magic dispel, it would be fair. If you change everything but keep mages as they are now, of course...
What grounding bug do you talk about?
