My suggestions

Here's a list of things to consider:

• Increase drop rates on MVP and Miniboss but leave the card rate as it is
  
• Remove the use of BWing in PK Arena
  
• Put up a PVP ladder
  
• Grape Juice in Tool Dealer instead of Chocolate
  
• @go, @storage, @whereis commands should be enabled as Michi suggested
  
• Old Soldier (Linker) not linking right. Make a poll if it should be removed or fixed
  
• Fix the lag
  
• And lastly, the Bot Police is quite annoying
