I don’t PvE at all, but in PvP enigneer is very good on point.
I use 3 kits, medic kit, elixir gun and bomb.
Shield and Pistol.
You must get used to kitswapping.
You can clear points really easy and have alot of heal output. Spec into protection duration on gear and alto of toughness, don´t go for HP.
Otherwise you also have the high damage Rifle spec, crit for 6k is not too bad imo (crit 2.3k+ normal shots) use berserker amulett and rune of divinity, then you should be able to figure out the traits yourself. The ONLY thing that annoys me is that the number 1 skills on kits dont autoattack by default.
