If a max RT of say 5 days was granted, or max RT of 10 days but only the highest offense can gain RT yes, otherwise base RT is not enough to play the game. WCS already stops RT purchasing forcing proper RT management, CP caps are there to let you walk away for a day if you need to and not feel like you wasted a ton. remove CP crates and RT crates, set RT and CP caps higher and I think you have a fun server - but it has to be pay to play with a significant sign up minimum or it would never be instituted. maybe someday the full source code will go open.
Edit: i'll offer an edit to say if you think the best players are buying resource crates, you have no idea how good some players are. The only crates purchased are CP to continue farming/digging depending on the server ruleset.
