Hello,
regarding Druid/Warlock, Druid/Rogue,
I tested both classes a lot over the last weeks and i just cant see them as useful dps at the moment.
D/wl is just too "slow" and cant keep up with the pace thats given by all the other classes. Aoe dmg is also not comparable with Mages, Warriors and Scouts. If D/Wl should be played in Mdps gear then it needs some changes to deal faster dmg and get some more aoe dmg. I didnt test it in healer gear but u doubt theres anything different.
Druid/Rogue has some huge potential, in single target as in aoe. The thing holding it back is in high instances the single target dmg is too low and maybe another dmg dealing skill.
Please consider buffing those classes and make them useful.
Greetings
