I have to admit, as a returning player I expected more... its very lackluster, more grind, more garrison like boredom and poor implementation of Mythic Dungeons, my wife was looking forward to trying Mythic Dungeons out but she hasn't played since Highmaul. She has around 668 item level roughly (which is fine for Mythic Dungeons) and her main reason for renewing was the Mythic Dungeons/Timewalker and the Shipyard (which she loves I might add!), sadly she found nothing but negativity and childish behaviour from the 'premade' finder.
I'm quite disappointed personally, I was flabbergasted when my wife told me of her morning experience with the premade finder, curious about what my wife had told me I renewed my account some minutes later so I could poke around the new patch myself. I took my alt (who is ilvl 672) and started to look for a premade group, I got an invite immediately and the group demanded I link the achievement for the mythic dungeon along with my ilvl and spec, didn't have the achievement so I was kicked from the group, not before one of them called me a 'Fucking scrub' though.
Looking at this now, Blizzard should have just made it part of the random group finder and stuck a 660+ item level requirement on it for queueing because its clearly just promoting negative arseholes.
Thoughts about the system so far?
