That's when you get back into the discussion of what is a "creative solution" to a fight vs an exploit. Like voidwalker tanks on Sartharion and kiting Eregos with green drakes. Regardless, now you've all made me feel squirmy about healing through the wall and I'll have to do it the hard way next time lol. Maybe I just need to level a second holy priest :P

Now to put the thread back on track: I noticed that the guys who dual 5 manned horsemen tanked two at once. Thane and Blaumeaux together, Rivendaire and Zeliek together. This would give you a bit less to concentrate on. That said, my group hasn't made this method work (or any other for that matter) but it's worth a shot.
