If you continue to dumb down the game, you will lose half your player base

Plus the game is more popular than it's ever been. Claiming that half the playerbase is going to vanish just because they're fixing button bloat is just the worst kind of hyperbole. It won't have a negative effect at all.

WoW was at its height at the start of WotLK, but at the same time they started a new motto "Bring the player and not the class". They simplified classes, and homogenization across the board. They began trivializing non-raid content.

Blizzard stopped reporting subscriptions during WotLK, and the player base began to decline as the expansion grew older. Everything came to a head, and exploded in Blizzards face with the release of Cataclysm.

SE is just repeating history with Endwalker.
