I Kinda agree it ruins certain part of team work in this Game specially But... not sure if Disabling it is the Best option
I was thinking to dual client a cleric+any other class
but so far I'm enjoying being a FS healer muse without a dual client and it makes me more active during parties leveling up,
I saw many AFK's and I can't tell if they are on dual client or actually AFK ,
some players are nice , they tell us they will AFK , but other's just AFK (dual client) leeching etc..
Maybe devs will come up with a Better idea for this
