Worgen cannot pick up Angelic Feathers while Darkflight is active

As title says, Worgen players cannot pick up angelic feathers (Priest talented run speed boost) while darkflight is active. In the past this has made sense as darkflight and feathers were both 40% run speed boosts and did not stack.

However, there are two issues now:

1: It is now possible for feathers to be talented up to 50% run speed boost (as oracle). This now means the feather should be a stronger run speed boost than darkflight, but worgen cannot access it while darkflight is active.
2: Next patch darkflight will stack with other run speed increases. Not a current concern but this should be fixed prior to that patch.

In addition, if you have the buff from an angelic feather and then activate darkflight, the buff for angelic feather is immediately removed. Tiger’s lust has a similar problem in that while you have darkflight active, you cannot cast tiger’s lust onto yourself, though you can cast tiger’s lust first and then darkflight. Both of these issues are replicable on the 11.0.7 ptr.
