well i found hc hard in 700+ ilvl and as healer/tank/boomy the boomly to get a real dps out of them for boss fights is just to low to burst and kill + moving on a boss your not really doing much dmg in the end i normaly wipe due to much aoe on the floor and nowhere to go. with 3 hunters though at 670 ilvl hc's seems really easy.

nromaly i just play them all as cats for wpvp.
