I'd like to hear yalls thoughts about concerns for upcoming Dracthyr in 11.0.5 PvP content.

(All these are concerns from WoW Forums)
1. Concerns about "Glide will be game-changing(aka ignoring Knockbacks,Slow effects)"

1. Concerns about "People being forced into race changing to Dracthyr(Dracthyr becoming "meta" in PvP)"

2. Concerns about "Having two extra CCs on top of classes already existing CCs"

3. If you have any other opinions please feel free to say them.
