You don't know what you're talking about, or how the "exploit" works.
macro char puts nexttarget to monster, think hes6safe, put a dumb aoe which attack both monsters + players, i.e non-target aoe, or aoe which leaves an effect in the area.
Macro char turns flag, "exploiter" pulls macro away, uses agression to make macro target him.
Now, if the macro char is using a bad macro he will not leave his target, thus making him vulnerable to PKing if "accidentally" using a skill as the other char is flashing white.
No exploit involved, ive pked MANY times in pvp because my opponent is running and i use a skill just as they pop to white name. Should i report those players for "using an exploit"?
Or killing a "red" just as he dekarma, making me red in the process..
Lmao.
The bug you're talking about is this :
Player flash purple to white, takes 15 seconds to fully transition between purple and white.
If you use a skill at 14.9 seconds, it will initiate cast while purple - finish while white.
Same for red, if you start a cast as they're red, then they turn white while casting > you will flag or pk.
There is NO EXPLOIT REGARDING AOE ATTACKS, just simply using game mechanics to make THE MACRO TARGET THEM.
Then they USE THE EXISTING, 100% WORKING PVP SYSTEM TO TRY N MAKE YOU KARMA.
Read above.
Long story short, dont afk macro if you don't know game mechanics.
