PvE builds for dungeons/solo?
For me I have solo just as well with rifle and I do with pistol and shield. The main thing I do for dungeon is select the gear that will help the most. For example I am going against a boss that is mid to close range and move faster then me, I wil break out my net turret, elixir gun and rifle for CC. If I am going against a lot of trash mobs I break out the flame thrower.
This is just how I role
For world PvE, AoE is king, and hence I’d suggest having either Grenadier or Coated Bullets. Or possibly Flamethrower/Juggernaut, but I don’t feel comfortable with the FT, so no insights from me on that front.
For dungeon bosses, I feel engineers are not particularly suited to straight single-target dps, and due to the unshakable/defiant mechanic, our amazing CC abilities are also severely hampered. Hence, I’d recommend going utility/support for them, sorry. Grenade spam still does decent dps and stacks a ton of vulnerability for the team, so that’s not a bad thing to run, if you don’t mind the lack of autoattack.
Dungeon trash would be the place to shine for a DPS build, as both AoE and CC are helpful and effective, but who cares about performance on dungeon trash, assuming they’re not skipped outright?
