yes. there are collectibles that are remix specific and i would imagine the heroic and mythic raids are so trivial at this point you wouldnt have much difficulty getting those titles. but of course the decision is up to you on whats best for you.
i have recently seen people say that you can Queue for Frost lord ahune and i was wondering if there was anyway to Queue for actual dungeons under 10 using macros, dungeons such as Ragefire Chasm and Westfall (7+) or Wailing caverns and Shadowfang Keep 8+) any answers would be appreciated...
