Class suggestions for "Death to the Corrupted" and "Death to the Dominion" Achievements

Being now a Thief main (formerly a Reaper main), I've been finding it a little tough clearing out the larger groups of Corrupted/Dominion during the Northern Part of Drizzlewood, especially in maps where the meta isn't really running.

I'm curious about what some suggested classes may be. I'll revert to reaper for these achievements if I must, but am interested to hear what others are running to do this!

Honestly just do them while doing the meta imoYou get so much more for doing the events and getting a bunch of commendations.
