Guild Wars 2

So, I definitely want my Tempest to be a tank for raiding, but I want to be able to heal as well. However, I’d like to be able to swap roles mostly through swapping traits and weapons, not all my gear. Obviously I’ll have to make SOME changes to drop/raise my toughness as needed, but I’d like to keep most of my ascended gear on instead of having to carry around a set of exotics (no way in hell am I gonna have a second set of ascended gear any time soon).

Right now I’ve got Settler’s trinkets, Minstrel’s weapons, and a blend of Minstrel’s/Nomad’s/Cleric’s armor (I wanted full Trailblazer’s for tanking, but the stat change is still bugged). My gear’s not where I want it to be, but before I commit to buying/farming for insignias to stat change it all, I need to decide which stats.

So, what would you guys suggest? Could I still be an effective tank/healer with all the same armor and just swap weapons/trinkets? If so, what would work?
