Ok so I have been playing for a few months and for someone who sucks at pk and sucks at bossing. There's not much to do.
1. Dice bag.... it's such an easy system to add I'm kinda surprised we don't already have this. Not only is it a great way to spend time when your super bored it would also attract more players and probably cause a rise in cosmetic items as well which is currently pretty dead.
2. More bond shop items... this would also drive the price of bonds up and also increase the amount of bonds purchased.
