I know this is an opinion question, and this might be the wrong forum so I apologize in advance.
I'm a relative newcomer to the game, a MoP baby to be precise. This tier - SoO - I have gone through 3 guilds, one that was 6/14 Flex (as progression), then to another where we went from 11/14N through 8/14H in 3ish months and now to a 10 man guild that's top 3-4 ranked in Oceania, just swapped to 25m and 11/14H in 1 week.
So no, I'm not hardcore, not ever going to be. In saying that, I hope to be tanking throughout WoD, and will be working towards realm 1st/2nd/3rd.
I main a Prot Warrior (and I'm feeling positive for WoD with this spec). I have a few DPS alts at 90 but no dedicated tanks.
It's been pointed out that I'm the only tank player most people know that doesn't have all the tank classes as Alts at 90.
So my question is - should I be working towards that for the new Expac. I know we know SFA about WoD, but as a general crossover from Expac-1 to Expac-2 is there value there to have another tanking class. Should I be gearing (legendary quest yadayada) a second tank class throughout to cover off issues where classes are poorly implemented or others become flavour of the month?
I want to hear experiences from people - not just "do whatever you want, it's your game". I will be going for guidance from my raid leader on this, but I'm also looking for experiences of people who have tanked much longer than I.
