Yay, Hera gets another tank. 1H and 2H share the same skins/buffs(Frenzy Buster/Guard Barrier skill lines) but not the same passives. Basically, you'll get to skin no matter what.
Warlock is a good sub for warrior, and there is a guide here at SRF for it, but there's a few things I disagree with (ie. robes, heavy armor is a must for tanking mobs 10-11 levels higher than you.) But maybe it can help you some with the warlock subclass, so the link is
HereIn my opinion you should get 1H first and pick up 2H for pvp or something later. 1H gets preferred in parties.
