Awesome guide! My AoE Commando utilizes GWell to keep everything clumped at all times, using Nebula w/ the crit enhancing skill while NStomp keeps anything from scurrying away until GWell is charged again. I also try to take advantage of the brief damage bonus from our +m/s skill, but it's tough to time. Also, I take so much damage because no shield/dodge/armor boost that without and engineer, life sucks. I think I will take some ideas from your AoE build and respec my Commando.

Thank you so much for posting this guide!
