IMO, the real problem with survivability is that we don't take enough damage to make our healing worthwhile. Whether that means that enemies should deal more or that mitigation caps should be lowered, I don't know. Either way, though, there's balancing that needs to be done on an across-the-board basis. I'd be hesitant to spend too much time thinking about reworks to individual skills until after the broader-scoped stuff is done -- barring certain skills that are clearly outliers in some way or another.
Anyway, I feel like the healing from Noble Mark is actually a reasonable amount. More than we need right now, maybe, but that's a different problem. How are people feeling about the damage component, though? Specifically, it's meant to provide a steady (if small) stream of threat on a single target... yet, in almost all cases, that's not really necessary. After all, we've got Threatening Shout and Grave Wound to build up a threat lead with. Even assuming a circumstance where those two skills have to be used on targets other than the guy you've marked, is Noble Mark's damage providing enough threat to be noticeable?
