I'm in favour of buffing the old Ward pacts- they need it. As was said, the whole scaling with party members thing is a bit what. I dunno who suggested it >.<. The useful newer Blood Pacts are fine. Thing's like Heavenward Howl will always be useless, so no point going into them.

Regarding Avatar's Favor, and similar ideas into an "stance" type ability... I had always hoped that SE would make an opposite if you like to Avatar's Favor. Maybe something along the lines of "reduces Blood Pact: Rage timer for increased perpetuation cost". That's what I think most people are crying out for, myself included. Would it break the job? Not really since you still have the MP pool, are using more MP through perpetuation and would be using Blood Pacts faster, meaning your MP gets depleted faster that way too. Even if it's -15 seconds, it's better then spike damage every 45 seconds. It wasn't mentioned, but before it is- damage dealt per Blood Pact does not need an increase. It's fine as it is.

Now onto Avatar's Favor... I personally don't use it, unless our healers are in real dire need of as much Refresh as possible. The 10' range is a bit... weak, but buffs are OK for situational use. You're not supposed to fulltime Avatar's Favor, it's just another buff option. Although I'd agree, the potency should not reset when you perform an offensive Blood Pact.
