As a dark knight I don't mind healers tossing in some dps so long as the party stays alive. Only time I don't like it is with whm using holy spam right after I pop blood price stunning the mob or when I use TBN and they use holy. SE needs to fix how holy works with drk BP and TBN skills. In 24 man raids, if I am the MT I do prefer healers heal more for me and the group. It gets old seeing two healers dpsing like crazy and I die to a lack of heals. I generally will say something when that happens. Also if they aren't healing the dps and the dps end up dead to unavoidable damage it is annoying. Dead dps don't do any dps and that is dumb when it is due to a lack of heals. They have one job, heals. If they can and want to toss in some dps as they can, then good. if not, no worries, dps should be doing the dps anyways. Just my two cents.
