Explosive trapper needing help

I sold an Aegis near the beginning of the league and used the left over to start an explosive trapper. I follow Jungroan’s guide and was looking around PoE.ninja. I feel as though my character is at an awkward spot. Map bosses are easy, 4 conquerors are not a problem, maven invitations get a little spicy. But I feel oddly squishy. Level 93, resists are fine, 4K health. Now that I think about it I’m sure it’s a problem with spell suppression or something but thought I resolved that. I’m at work so I can’t link POB (not that I would know how anyway) but I’ll try to edit it later.

Just would like to try and reach a “goal” of finishing and farming bosses this league. Anyone able to think of something that I’m just overlooking? Do I just need THAT much more crit multi type mods?
