Too many useless regions?

there are way too many regions that have basically no use considering that the level cap is only 20. even if i used 1 region per 1 level i would have still more than the half of the remaining regions without a use. i would really like if the level cap would be something like 40 or 50, or maybe even customizable

It’s often really useful to have multiple regions per level - especially the early levels, as you’ll have a lot more Level 1 players than Level 20 players. Having multiple Level 1 regions also means you can space out your entry portals, to stop regions getting overwhelmed.
