Guild Wars 2

I had an idea for a mostly defensive/support traited guardian with some power+vitality/toughness armor to lvl with… I am accustomed to playing face tanks in other MMOs (guilty of playing a prot paly on wow, pulling aggro and then leaving the room while the group kills the raid boss). Now I know that is clearly not possible in this game but with this type of build, and if i keep my gear updated, could I at least pull large groups and tackle them to speed up leveling? I used greatsword up to 40s but it got boring. lol, my other character is a thief with mostly power/crit traits for my dps side…

just curious if anyone has tried this and if it works for my goal.
