Agreed, slowly the +10 status is becoming quite common, it's not as impressive as it used to be. Getting to +10 used to require work (literal work, the one where you earn money), and now any player can achieve that. I think it's time there is a successor to that status.
What's even worse, +10 is slowly becoming a REQUIREMENT. How many times were you turned down because your amp level was too low and everyone else wants to 1stam a dungeon? By increasing the amp cap, which will be unreachable by majority, said majority will realize that high amp level is not everything, and the growing elitism will be culled for a long while.
I also agree with Sulla, +2 seems odd, a multiple of 5 would be good.
