The loss of reviewer feedback in Wayfarer

I LOVE the new system but I do not understand why the need of old reviewing system need to be removed.

This is actively rewarding bad reviewer because if I am reading correctly

This mean, a bad reviewer can have same voting weight as a good reviewer, which feel really unfair. Hypocritally, if I want to get the platinum medal, the best way is to spam “no” on every submission I want to review. Obvious this is an extreme case, but the fact that it can happen concern me.
