Hello i like the idea going back to classic and trading eks for currency its good move, but not for very rare items which affect a lot in pvp.
About hf its so hard to tell first thing is that its very easy to ek and exp with that spell to be honest both too super easy for ek and exp , but at least mage can exp on every pit not only trolls this gives a lot more fun, without hf also can exp on ogre or ww something ,but its painful too boring take a lot more time. So why dont make it super rare, If its super good not like it was before, a lot people have hf and it was not good, if a lot players get an item its not rare anymore its common and hf was that item at the end!
About conclusion just for the whole game, its simple make drop very low 2x lower than you want to do now, because this is what ruined every server not high exp but too high drop. If everyone have only shop items this is fun! Because everyone fights in middleland no one hiding all have a chance for win. When people get a lot good items too fast they got bored an leave"its fruit server and it will not stand long , we dont want that" But FIRST thing is that when we got a lot of players with cool stuff like ridiculous high mr hp mp set. Than at this point server losing players, because normal player cant stand a chance with peoples having sets 70+, he will die couple o times than he leave, cause 0 chance for win so whats the point in playing?
The Goal is only one maximize the time before players get too high items, otherwise newly character with 0 items will leave. Until people still finding items, thats the server chance will gather more and more players, always after that there is less income, when everyone will saw on chat "trade sb gbh xneck x ring set hp70+" they will not play the server.
