Sort of back on topic, just wanted to toss around random other ways in which I could see some things fixed up -
:: If they really don't want to do BL charges (if, for instance, the 1s recast minimum is not something they can circumvent), they could axe the level 68 trait or change it into some other benefit like EA getting some song-based bonus.
:: Alternately, if there's an issue with Bloodletter code specifically, we might see an updraged version of BL that happens to have 2 charges. This would presumably have to go hand in hand with upgrades to PP and Army's as some sort of "song mastery" trait or something.
:: If there are no plans for other Muses, they could at least mitigate the PP expiration issue by changing PP's cooldown to 1 second. Not a great answer but at least you could try to (GCD - PP - GCD - PP+MB) and if you ghost at least you didn't waste a full three stack.
:: Increasing Raging Strikes to 20% would be a simple but fairly healthy thing they could do, though at an 80s cooldown ideally it could be 25s or 30s to make double snaps sensible.
:: If they wanted to cave to the demand for a Foe revival, it'd probably take the form of an ability that spent MP but didn't drain it. But then they'd need to add other MP interactions to the kit, and that would lead into Energy Drain sorts of issues, so I'd be surprised.
:: Warden's could always be reworked into Palisade or something, though as noted before I'd rather they look for more non-hamfist ways to have white bar debuffs
:: Wouldn't hate a charged-action version of Battle Voice to make it a little more distinct, or a big upgraded version... really there are tons of ways to make it a defining premier skill, rather than an afterthought.
