I am guessing that 7.3.5 and RAF nerf have impacted your leveling strategy? (and/or motivation).

If you are still going, I would love to get your observations on just how hard these changes have hit. I still hear some conflicting news (for instance while Bliz states XP bonus is capped at 50%, it seems some have been able to use guild banners to get over that, and rested seems to still stack, etc.).

I was intending to level a lot of groups (like you) and hit the guild class achievements. Now I am contemplating some round robin open world boosting to see if leveraging the rested XP along with my heirlooms and guild banner can work (only playing each group once per week until the rested XP is used up and let it recharge while moving to the next group).

I am not too hopeful for that strategy, but I am just trying to make the best of what they haven't nerfed (before they nerf it too).
