Tend to agree here. They really should have known it wasn't great when they had to start adding caveats like not including fire totems to make it viable. Clunky design like that should have set their alarm bells ringing and as someone mentioned before, if it wasn't workable during MOP beta, why is it now?
It's almost like they wanted to get rid of TR but didn't have anything to fill the spot so just ressed an idea that wasn't great, but would plug the hole in the talent tree and let them pull TR. Perhaps we'll see some improvements later on but for now, I can't see myself ever picking it.
Oh, and did they ever say why TR became a focus for removal? Did the other classes lose their Prep type abilities and they were just clearing them all out or something?
