DW or 2H is more or less a matter of taste these days I’d say. There are strong builds with both. In general, Purifiers are doing really fine. So you have a lot of different flavors to choose from.
Here are two builds I play myself.
mad_lee’s “Top Gun”: Very easy to play, 5 buttons including movement skill. You basically just shoot things.
A bit more buttons to press, but great fireworks:
“Inquisitus Deletus Criminalus” by the jabrixone. I really love this one. But mad_lee’s build has less buttons to press.
Welcome back to GD!
