You mention boosting to 110 after you hit 60. I should mention there are no longer any benefits to waiting to level 60 before using your 110 boost, no professions, no garrison, nothing.

In BfA, the end game dungeons seem to require a trinity setup, or at the least 4xDPS 1xHeals. My 5xHunter team can clear more dungeons than my 5xTank team, but its nothing like Legion, need a heals.
