For me the server would be more fun if they made all spells usable, which mean that abilities should be blocked
fully because it's to OP. Maybe the Administrator could unblock all spells and, if it's too OP, just nerf the damage scalability of that particular ability. In some servers (bear with me, I'm not trying to advertise or anything :P), maybe the server i know best that nerfs OP abilities and yes if the spell is too weak they buff it, AdverseWoW (formerly CataWoW).I know its hard to do maybe but if the Administrator can do it, he should. For me these changes would me experience the server more fun, and also add strength to Druid gear, it would make bear form more useful.
P.S., tell me what you think :3 ( Sorry if my english is not very good, I'm bilingual so bear with me)
