atm i feel the grind is too small. i'm not saying its too easy to get to max level, i love how currently it doesn't take days and days of grinding to reach the top, it would be nice if there were things to grind after you reach cap though so you have more reasons to play said character instead of for raids/events/tourneys etc
here are some ideas
10 000 000 exp for 1 skillpoint, can get at tsuande. can be done 3 times
after hitting cap, doing 1k s/a/b rank missions brings your defense up by 0.25%, up to a cap of 3%
idk what else or if these are op or what, i just feel like atm you make a cap char, make an alt n rinse & repeat. would be nice if there were things to do on the cap character
