To me the max caps proposed as it some people will likely max everything (no matter the pay level into the game) within the month of playing in the world. Given the max I have seen over hmmm 2-3 years liekly 4 max is about almost 4k... I would think that makes a good life span for the world and gives a max cap for everyone.
So why not make it
4k Max for paying players
2.5k for subscribing players
1.25k (or more) for non paying players...
There needs to be this feeling of growth but speed wise I rather just see the speed differnces, and a world cap of 4k lol.
