I politely ask why the ability to not mark runes in dungeons was installed in the first placee.
I'm not privy to the reason(s) why dungeon recalling was nerfed on Evo but I do know two very good reasons for doing it on most servers. One ties in to part of Sagemoon's comment:
I am also concerned about AFK farmers running rampant because they cant be so easily discovered
A farmer standing in one spot AFK waiting for respawn is not good but is vastly less of a problem than players AFK recalling from one dungeon hotspot to another, running an auto-attack/auto-claim script, leveling weapons and making a fortune.
Another reason is that it makes PKing and ruining people's days so easy it's a joke. Hit thirty farming spots in sixty seconds? No sweat. Then do it over, and over, and over, and over for hours, days, years, so that no one can even dream of PvMing anywhere worthwhile in relative peace.
