So we got to this fight Tuesday after downing the first 3, we have the main adds under control and towers but the problem is the demo crews. The adds seem to die so we ended up sending a healer to heal the adds along with a DPS. Now we are doing the fight again in about 30minutes and I was thinking of trying to send 2 DPS that were not part of the Tower crew to take care of demo crew's on their own and if they needed healing on the adds have a healer run up to the demo crew and heal. What is the best way to handle this mechanic?
