If you’ve played wow for so long I would’ve thought you’d see a pattern with blizzard having no idea what direction they want levels to go in.
After wotlk, blizzard became the most inconsistent devs we’ve ever seen.
Vanilla, level 60 Healthpools 4-9k.
TBC? Level 70 healthpools 10-20k, new talents, new spells. ok, +10.
Wotlk, Level 80 healthpools 20-40k new talents, new spells. +10. pattern established.
Cataclysm. Level 85 healthpools 120k and up, no new talents, but trees rewritten a little, and restricted. New spells. +5, confusing, pattern broken.
Mists of Pandaria, Level 90, Healthpools breaking 500k, exceeding 1m in some cases. Talents removed and redesigned. New spells +5 levels again. Confusing.
Warlords of Draenor. Level 100. Stats Squished. Healthpools reflect the previous expansion, similar numbers. Abilities Pruned. New talents. Classes dramatically redesigned. + 10 levels. New design.
Legion. Level 110. Weapons Removed. Stats bloated. Millions upon millions of health. New Talents/Talents redone. PvP talents. Artifact Weapons. Classis all completely redesigned, and abilities pruned again. +10 Levels. New design.
BFA. Level 120. Wepons Returned. Stats Squished. Health lower than its been in more than 30 levels. Talents reworked again. & Less PvP talents now. New necklace. Set bonuses Removed. Magical Gear scaling. Hidden math that isn’t explained. Lots of broken, stacking traits. + 10 levels. New design.
Why exactly are you worried about a stat squish? Nothing has been the same for any length of time for a good long while now.
