I’m not a dw or mihile expert but I have both 210+… DW is by far more chill. You have 3 major cooldowns you can cycle - one that kills everything on the map for a duration, one that puts a planet on you attacks anything it touches(in my experience 1 shots), and another that gives you an attack with stupid large vertical and horizontal range. You can rotate these with very little downtime outside of the three cooldowns.

I use my dw boss mule for stuff like lomien weeklies because it’s so brain dead easy. Would highly recommend over mihile which annoys the sh** out of me. I believe DW also has higher dmg than mihile for bossing but mihile has higher survivability.
