skills after lvl 50.
 

The skills that are raising atk(weapon skills,offense) and ac(defense),dont raise ac and atk after lvl 50,when they are at 210+ i think.

55 War here, some of my skills are at 240 now, even 245 i think.. dunno why my ac and atk arent going up though.

The client is jsut not displaying them as going up for some reason. The server is still increasing them correctly, you jsut can't see that because the client does its own independent calculation that the server has no control of. If you have enough access to do #showstats you can see what the server calculates it as.
