Pk scroll or no-pk scroll is a key thing in this game,i really dont understand how u could put something like this in a shop that till now was a pve shop.
Casual ppl is already affected by your ridicolously fixed server,with this u open the way to harrasment from high lvls and strong cp.
Bot businessman could just lvl some high lvl and protect bot spot pkpping ppl 20 lvl less,this will lead to a game more annoying than already is.
