First Boss - quick swap to the toons that have decimation and move them out of the group and then /follow back to lead, OR - just strafe your whole team to the side.
Dogs - You should be fine to just stay stacked for this fight.
Portal Keeper - Either send your whole team through the portals, or don't send any.
Eonar - You can actually avoid using the special action button altogether if you just use the boost ramps to go up/down
Antoran High Command - just stay out of the pods
The Hunter - P1 - stay stacked, P3 - pre spread your group so you don't get knocked around
Kingoroth - Spread a little, and kill adds.
Varimathras - stay stacked, move out of purple
Coven - Spread for lightning adds, focus healing adds, get out of middle for fire adds, don't let line adds touch you - don't stand in anything
Aggramar - Stack on tank for technique, loosely spread - strafe out of puddles
Argus - you can stay stacked for most of this - once a character gets targeted with a bomb - move your toons away from the raid. Release when the last phase starts. Stack - move toons across the room if you get targeted with bombs.

This raid isn't too bad, LFR is pretty garbage right now because boosts. Also - avoid LFR after Thursdays. It's pretty crap.
