Vergalid Mines: Vergalid's End

Try pinning him higher up on the wall and have raid below him helps with the AE's some it seems from what I can tell. I have never got the add AE and if the tanks keep him high on the wall I almost never get the crystal cure one.
 
SOE put small faction hits into the AG raids like FC. Does anyone know if the Verg raid gives faction to either side of AG or is it just the AG raids themselves?
 
There was faction on the connecting quest. Pretty nice at that. Anyone have a winning strat yet ?
