Currently, I'm Ret, have 4pc T10 and a Brynntroll (normal). I've been considering switching to Prot, but since we're in the doldrums before the expansion hits, I'm wondering if it'd be better for me to just stay Ret, maybe work on getting a Shadow's Edge and fill out my gear more, or make the jump into 25-man tanking. My tank set currently gives me about 37k health unbuffed, almost all triumph badge gear and some pre-ICC raid drops.
Any advice on if it's really worth making the switch at this point in time? I'm not currently in a raiding guild, but can usually find pugs that can clear up to LK on 10-man and Putricide on 25.
Any advice to help me make the best decision would be greatly appreciated.
