Exsqueeze me whilst I bounce up and down excitedly .... but just LOOK that that pretty mount!
Blizzard have announced that patch 6.2.3 will soon be up on the PTR and it lots of fun new tweaks in it:
- New Timewalking Dungeons
- New mount that has a random chance to drop off ANY Timewalking boss
- Cross-Realm Mythic raiding
- Valor Points are back .. together with the ability to use them to upgrade gear by up to 10 ilevels
- New mount and questline from Archimonde in Hellfire Citadel Heroic or Mythic
- Better gear from Mythic dungeons ... now with a chance for ilevel 725 drops, plus the chance to get an Heirloom trinket that scales to level 110
- Improved Baleful items from Tanaan drops .. now with a chance to be 695
- Arena Season Transition.
Please do note this is all still in the testing stages and is not guaranteed to make it to live .. but we can hope
