The experience required to level from 1 to 110 has decreased substantially on the PTR, with extremely small changes to the 110 to 120 experience. The following chart shows just how much the experience has been lowered. https://www.mmo-champion.com/content/8151-8-1-PTR-Leveling-Experience-Reduced-Fifth-Azerite-Armor-Ring-Added-Raid-Testing
"extremely small" changes? that's not really...um, that encouraging, but thanks
110-120 is extremely small, and that's fine.
It's "current expansion" so if it's slower, that's to be expected. But all those prior 10+ year old stuff doesn't need to take longer than current stuff.
The timing is good, and bad. I haven't leveled a new toon since June, Just yesterday I created a Goblin Warlock. Then last night I read that, if I wait 5 weeks, every single level will be faster. From 60 to 80 it will be 40% faster.
I know I should ignore it, and just enjoy leveling. But I also know that I will be constantly thinking "this would be 40% faster" and will enjoy it less.
