Tab DOT is about all Ive been doing on trash and dropping treants to speed things up when its available. I have the moonfire glyph so it hits hard stacked up 4 times. Its doing about 1300-1400 a tick combined where insect swarm is about 700-800 a tick combined. The mage group could AOE about 3 pulls of guys then have to drink. Maybe 15seconds a pull then 30s drinking. This group its a couple minutes a pull, but they never have to stop but to rebuff. But its WAY slower.
