IMO one of the major things that would improve classic would be to simply add more stats. Right now there are 4 stats and only 2 of them only really matter for anything and those are Pks,Sparring.

Baddie kills are only good for your first 100 to allow you access to certain towers, otherwise kind of pointless and not as sought after as the other 2 stats.

Hours or Online time at this point are even less useless. The only thing they do is get you access to certain rooms that don't seem to serve any real purpose other than allow for global farming and that isn't very safe because who knows when some one will come along and steal your gralats. They are not a good measure of actual activity or time invested actually playing the game. You can see ppl just idling in lots of different areas in the game. For instance you can go at almost any given time and see some one riding around the rails with a message above their head saying asleep afking for hours.

Sparring and Pk's are both obivously the most used stats in the game.

With that being said I don't understand why more stats haven't been added yet. I think it would improve certain areas of the game if you could keep track of more stats. Ranging from bugs cought,total time being in guilds. (that would start from the moment when you first put on a guild tag until you take one off,and would start again when you put a guild tag back on.) There are probably several others I haven't thought of that could be used.

Imo they could change the player profile consists of your avatar pic,status,messeging options as well as a sub menu dedicated to showing only a players stats that would be an option you could go into when clicking on someone's avatar. Not just a "player card" screen with 4 stats and an editable status.

My bad 5 stats sry i dont count gralats because idc how much gralats ppl have.
