I have been thinking of an idea to make the imp ss desirable in raids and even better for enhance for pvp. Change the improved ss to make it proc a replenish. I know there are other classes in raids that have replenish, but look at the name of an "enhance" shaman. I don't take imp ss for pve due to raid buffs, but if it were a replenish instead of a base manna percentage, then I would be all for it. I do understand in a ten man your more than likely to have a ret pally, shadow preist, or a destro lock, but how offten do you see a raiding frost mage? most of them do not. no other melle class that does use manna other than a ret palladin has it due to use of rage/energy/rp and I believe it would be a huge addittion to the enhancement tree reguardless of your choice of pvp or pve. I dont know the developers aim for improved ss after 3.0, but I dont see it used much as an enhancment tool and I feel bad that its wasted (atleast on my toon) for more damage on my lightning shield. It may not be a "waste" per-se, but i love to help other classes do more and it would be icing on the cake for me.
