I'm not saying RDruids are or aren't too strong, but comparing abilities in a vacuum like this never turns out well, especially when you present all tools as if they're equal. For instance, both cyclone and root have a cast time that you didn't present, does that make it a fair balancing mechanism? I'm not going to say, but just things to think about.
I really think thats just a case of mages being too tanky, which is why I suggested a flameglow nerf. I really don't think mage/rsham, mage/priest, mage/hpala are that great outside of rogues and sps. Decent comps sure, but not anything super dominant, especially when you take away flameglow
