Make Rarity on Waystones additive with personal rarity instead of multiplicative.

Rarity on Waystone is multiplicative with Personal rarity. Well in POE1 that is the case. So i assume its the same here.

The issue with multiplicative is that it makes really high rarity extremely broken, it grows exponentially.

If it would be additive that issue wouldnt exist. Thats why high rarity aurabots are so good. They can just abuse the exponential growth of the mechanic.
