I'd tweak respawn timers for zandalari warbringers too. They are never up and because of CRZ there's always someone camping the spawn spots even early in the morning.
And no, they are not shared tag mobs.
At least make them shared tag personal loot. Fighting for tags should be a relic of the past nowadays. This only makes meeting other players a nuisance instead of a good thing (like it should be in an MMO)
As for MOP world bosses i couldn't care less because their drop rate is too unrealistic for me to bother farming them. I just make 960k gold and bid that on BMAH. Got galleon and plagued protodrake mounts this way so far, it's only a matter of time to get remaining ones. And once you have 10 alts with garrisons it takes much less time and effort to make 1 gold cap than kill a weekly lockout boss 2,000 times on average.
They might change how gold works in legion tho. Inflation has been pretty high and i wouldn't be surprised if they upped gold limit in 7.0, or even made gold serverwide with no realistic limit. If that was the case, well... shit, because i can't "buyout" on BMAH anymore
