Look you obviously never played other mmorpgs such as MU and WoW
etc.. They are much worse..But that give more flexibility..And on
the player killing,the best would be a PVP arena but maple can't do
that for the simple fact that they have too little characters and
almost everyone is the same..4 classes how different can it be,plus
its a no brainer that mages will win..Lineage offers you the chance
to kill others,but doing it has consequences..Which i'm lazy to
explain..Overall a 2D game should not have player killing because
of the limited flexibility..
