That's a shame, what about if I was only to do PVE? An arsenal/bodyguard with the focus on arsenal but able to help out with healing (even only self healing) when the going got tough?
You have dedicated healers for a reason.
If you "have" to help out with healing which is rare but it happens you use your basic two heals.
It's just poor PVE play if you are gimping your dps talents and hoping the healers fail so you can justify speccing into healing talents.
