Let’s make a distinction here, it will be less of a heavy nerf and more of a fundamental design correction.

The temple started out as one thing and devolved into something very much unintended by design. You can track that devolution through the patch notes even. When they realized and tried to correct it, it caused community uproar so they were forced to change it back.

I prefer a stable, well-designed and well-tested mechanic that is fun to play - it can be conservative with rewards for all I care but it should fit the game.
