I too have been playing this on PC recently!
As for class, I am always struggling to settle on one, but currently playing a Pyromancer at level 19. Its kinda insane, but it can make a bomb out of anyone, whether I can see them or not. Through mods, whenever I do so, all those within range are “Ashed” (Cant move), and when the bomb goes off, everything dies. So - That means I can just stand behind a wall, not seeing anyone, and just use the ability to set off people as bombs - kinda insane!
