Well recently I've started and been levelling a resto shammy. It's been pretty fun and I'm really enjoying it. Normally my main is a Prot Pally Tank/Ret Pally DPS so this is a bit different playstyle. But now I have a question. How highly is the 4 piece t9 valued? Is it worth it to get the 4 piece and one 245? Or is it better for 2x 245, possibly three and just keep the two piece bonus?
