Chronomancer HoT gear??
It has been my experience that the mesmer has enough health to not get 1-shot by most modrem, even in Berserker gear.
So go with either Berserker or Assassin gear. I’m not sure which one. if you feel yourself too squishy, start swapping out pieces for something more durable, like Valkyrie, Soldier, or Knight.
I don’t have opinions. I only have facts I can’t adequately prove.
Besides what was mentioned, you can also look into Marauder’s, Wanderer’s, or Commander’s; the first one can be obtain easily by learning the recipes from craft npcs in LA.
