Roy's our boy! Rushdown and high pressure works really well for me, while I'm trying to learn the ins and outs of Byleth. Lucario is another favorite of mine, I tried out Joker but had too much trouble getting kills without Arsene which was very limiting for me.
And oh my, I haven't seen Diablo II in ages, not a big fan of the franchise but I definitely enjoyed that one, even more with friends... Also with necro.
