Yes, it is bad - I agree. But it is not isolated to resto shaman. Its the same for warlocks & many other dps, every other healer aside from Rdruid, every other tank aside from warrior. There is always going to be something that is slightly better than others and everyone will try to use it. Its a noob mentality unless you are an elite player. Start your own groups - don't fall into the mindset yourself and you may actually find people to play with is what I am saying.
