I think this update would favor the impatient, possibly take more away from ranks.

I would be happy to get the achievements earlier, but is it really worth taking a financial hit to all the achievements? Really shooting ourselves in the foot here, I think it's better to be patient and wait for the achievements.

Also, I think this takes a some of the motivation to rank away. One of the nicest things after you hit a new rank is to go see what new achievements you've unlocked. It takes away from some of the excitement of a new rank. 

I dont really see the point in it going ahead tbh.

I see the initial idea and its reasons, but why lower what we already get, just so we can get it a little tiny bit sooner? Seems pretty silly to me. And I mean that it seems silly from a player perspective to ask for that, not from an admin perspective to give the compromise like that.

Essentially, I would really dislike this idea to be implemented under the premise that the values are lowered.
