My main team is now 110. MW + PROTW + 3*MM.
I switched out of BM because fuck BM when questing. Pets are always in the way when looting / clicking things.
Class order halls haven't been bothering me as much as I thought they would. Yes, you do need to visit them once a day but that's generally it. A hassle but not nearly as bad as garrisons were.
Questing has been fun. At least once I specced out of BM. Pretty much the only time you will see solo phasing now is when you're doing instanced content. There you can park the rest of your team and do them one at a time. I pretty much did that on my main team.
Much better expansion than WoD.
