I feel a lot less stress about tanking than I used, especially as a Warrior. I honestly do not know if I am doing ok, better or if my healers are just making up for my lack of proper cooldown usage. (Most of the time, their MP is good, they're allowed to do some DPS. Some AST and SCH while I leveled in Library scared me though -_- One would let my HP go to 5k)
I used to BLM everything first, then SCH, then tank. I switched to SCH main in Heavensward, then WAR'd to 60 and now I'm starting to level BLM.
I think if you feel a lot of pressure, you can go non-tank first. Honestly, if you're using some cooldowns, not standing in every aoe, and keeping hate, I'm not going to really care about your performance as a tank. If you're new, say so. I wouldn't expect you to know the intricacies of the pulls etc but I will expect hate to not be lost or not standing in aoes. Some things are 'basic'. Knowing what to do in each dungeon when new? Not expected.
