Guild Wars 2

I stopped playing fractals, so I swapped out all my agony resist for +5 power infusions on offensive slots. My question is on whether I would get more out of +5 vitality or +5 toughness for all the defensive slots. I would have all the armor and I believe the backpiece and 2 trinkets. All gear and weapons are ascended berserker, and I use it for all types of content (except PvP obviously.)

I’m thinking the vitality is the way to go. With my con and guard buffs, that’s a respectable 23,000ish health for WvW on pure berserker, and it helps with condis. BUT, I don’t really understand the math of toughness. IIRC, and I have to run out the door, I have 960+ toughness, so it’s quite low, ad I don’t even know if that would be noticeable at all in dungeons. Looking for opinions!

Edit: Back and checked the actual numbers. I have 2 trinkets and 1 amulet and 1 ring that are defensive, plus the 6 armor pieces. So I can get either 50 toughness (currently 946) or 500 health (currently 17,744 with zero buffs active.)
