Tank has a very real hard cap in terms of how far you can go. While there are a few exceptions from time to time, it’s not something you’re ever go to be able to push with realistically. In the end, you have to ask why you’re playing and if that goal is achievable. So, what’s your aim for arena or pvp in general?
Not so much. Prot loses access to most of their defensive CDs when they have a flag, so they make bad FCs. I believe they were also neutered in output, etc. so they’re not even a good option for a ‘4th healer/DPSZ/base sitter’ anymore.
Absolutely. Great options for boss tanks in things like IoC, and AV, but can also be useful as frontline melee who disrupt, and punch holes in the enemy defense.
Grabbing an Arms Warrior or DH will probably be a decent comp for you. But 2’s is pretty deflated right now, so you’ll have harder games at lower rating than usual and might hit a wall early when trying to farm conquest (not to mention finding anyone who wants to play right now is hard).
Almost definitely better off just queuing Ret RSS to gear.
