Oculas and HoR seem to be high on my list of most hated and the "random" generator seems to find them all the time. HoL has never been a problem for my pally/shaman team and one of my favorites to get if I have to get one. I just heal through Ionar, make a box formation of the shaman and stop all DPS during the spiders and stand still, switch to my healer screen and heal anyone who needs it. I rarely need to ask my alts to heal themselves.
