Please remove 2 "minor" ambiguity problems from the game

1. It is impossible to tell what boss skills deal physical, chaos, cold, lightning, or fire damage and at what percentage they deal these damage types. It is still as opaque as it was in poe1. Please give us an in-game way to understand as players how to mitigate damage.

2. It is impossible to tell what Increased Item Rarity actually does as players. Please formally state somewhere what it does. Do not make this a "dial" you can tune differently from league to the next. Rarity should be something we can know "we've hit the soft cap of" without going to developer interviews and discord channels about it. At least IIQ says what it does.

Sincerely,
A Veteran Player Who Has Supported This Game For A Long, Long Time
