Loot is literally raining from the sky for me at the moment
-due to the patch everyone got 3x emissary quests
-Order hall quest for extra EN loot from eyeballtree (got a bonus roll third token)
-Weekly quest gives a box of random EN loot for running 4 mythics (got shitty 870 boots)
-sign of the warrior - extra loot from dungeon bosses that you're doing anyway for the weekly and Kara attunement
went from 869 equipped to 874 equipped, dont think ill be able to get much higher without Mythic stuff or my other legendary dropping.
Karazhan - fuck this place
Mythic+'s - i think the time vs effort is fine, you dont want to spam +10's all week just run 1 so you can get your free 880 loot and then run +7's which are quite a bit easier. 2 chesting a +7 gives pretty decent loot if you can spam them when it takes roughly 25 minutes to run through.
class buffs - Fury got quite a substantial buff, our resident Fury warrior went from 240-260kish to being number 3-4 on most fights pulling 340kish (some of this was due to gear upgrades)
Bugs - Horn of the valarjar that auto completes a world quest for warriors just despawns the quest with no quest progress
you could transmog legendaries for a bit yesterday, had a fury warrior rocking 2x shadowmourne transmogs in our raid. i tried after raid and it was fixed
