like others have said we lack an on demand burst ability, if theres movement in any encounter our dps suffers badly, as we have no way to counter it as eclipse is totally RNG dependant. On stationary fights I think our dps is ok, sure it could use a little bump, but its nothing worth worrying about, but seeing as most encounters need alot of running around switching to burst down adds etc, we do come low on the dps charts.
PvP well lets say I don't enjoy balance pvp we are a pretty easy target if they get in our faces, if we havent been noticed and can just nuke then we can hurt, But i prefer to heal in BG's anyway
