Out of curiosity, why is fearless being nerfed along with all the % damage amp masteries?

The resolve tree is already bleh.

fearless: 2 -> 1.5 bonus armor/mr per level

This necessary? Or is this supposed to be some "compensation nerf" so that even though damage amp is getting hit, resolve will still feel shitty to take? Are we to expect more resolve tree nerfs even though it's the worst tree in the game and is only used for courage (or grasp shen)?
