As a mirage mesmer, For kicks and giggles I decided to equip my GS (diviner's -> I don't keep pure DPS one because it's not really meta for the content I do with my GS build) on my sword zerker's set and in a random group we cleared TP DRM with 45 seconds to spare. We barely missed the timer on FOR (30s) BUT I died once and my team was constantly dying. I feel like the bosses on these DRMs heavily punish melee builds and almost all SC and DPS builds are melee heavy. Granted my randoms in the TP one knew mechanics, so we didn't die during spears and adds were light. But I think more people need to be running as close to pure ranged DPS as possible, if you have a ranged support build, I guess that works if you have pure DPS you can amplify on your team to a point where it's better with you + them as support instead of DPS.
