Well somehow that makes sense, sharing damage between group members causes no one get too big spikes. But tank was in full health when vanguard asked for taunt, and tank refusing to taunt enemy led to vanguards death. Maybe I should have took enemy in order to save vanguard but I don't have tools to generate threat on enemy fast enough
because dual wielder has random aggro so he wasn't on me all time. Most of time but not all time. Still, tank was only one who could have saved vanguard but he refused to do it.
After they kicked vanguard I really tought about leaving group
