A question about Shiled of the Dunedain, will it be possible to use the skill on ourselves? If not-why? Someitimes the healer is the one who needs saving. The initial class kit was well thought, it worked fine in the level 50-70 content, when its usefulness began to diminish and totaly disappeared after Helm's Deep.
No, Shield of the Dunedain is still an ally-only targeted skill. The identity of the skill is that you're able to use it to save an ally, and the reason it's shifting over to blue-line is that healing captains should be able to use it to save their tank. If you, the healer, need saving, you'll just have to rely on other defensive and healing abilities (Time of Need+RC, Gallant Display, MC, Gift of Spirit, etc).
