Although this patch was mainly focused on Ele / Engi, there are a few incosistancies between the patch notes and reality for rangers.
According to the patch notes priority is supposed to be given to players for casted buffs, that is not the case for pet f2 abilities. Still prioritizing everyone but the Ranger which is exceptionally frustrating.
Also, rapid fire is not letting you switch targets mid cast as advertised on the patch notes.
