You definitely need a bit more hp than you think if you do not always have a full support cast behind your lockers; also as mentioned earlier the aoe from Snorri is really brutal for low hp rogues. Had it happen many times that I die quickly from drawing the immediate aggro due to hitting it first or pulling with skills and eating his first melees, skills, and adds, only to get nailed with the aoe after respawning and timered. However much hp insures this doesn't happen is all you need imo, as as long as you are not timered you can be dishing out pretty normal dps regardless of curse and in a lock battle the very beginning of the boss is obviously the most important. Have seen no mention of spider rings so far, those are exactly what you want in a rogue locker. Being able to hot swap is optimal if you have the resources, although if you have a few good lockers on their game it will lock almost before you can move all your gear around and cast all your skills. If you look a few pages back there is a dedicated post to this subject with far more replies that includes a few very insightful ones; highly recommend you check that out.
