how you attain those numbers (very conditional; aoe perhaps ... if you let the sorc heal hit up to 600k.
On my phone, so I apologize for brevity. The only aoe in an Assault commando's regular rotation is sticky grenade. Maybe some other aoes for node denial. As for the Sorc healer - 600k isn't that big of a heal number, but for what its worth - this was a solo queued pug, so we had no coordination.
Also, the point of the post isn't about my skill - it's about the fact that it's possible to output performance (objectives, numbers, etc) keeping up with the rest of a random warzone while in fresh 50 gear.
