It's funny, being a swashy with a newb tank does suck a lot in the beginning of the game, but by the end of the game swashies can make bad tanks into superstars with the aggro transfer. Just hang in there
In the meantime I know your pain, I've been teaching loads of tanks how to body pull in Crushbone. Actually, to be honest, at level 20 being a tank is a nightmare. You don't have all your taunts, if you're a newb you probably get Apprentice IV at the max right now with the transmuting issues, but DPS classes still have pretty good attacks and scouts are packing mastercrafted poisons.
