The exploit has been fixed since the end of cataclysm/start of MOP. Countless people reported me and people I played with. Never heard of any of us get banned. However, the script macro was disactivated and no longer works.
Click macros are legal in my books, as it says, just acts as a mouse click. Scripts are the nasty ones. Regardless, it will get patched eventually.
I do not use it now nor will I ever again. Risk of leveling a 9 year old twink for 1 bg is not worth it to me anymore.
Also, the irony of this hate train makes me laugh. F2p/vets complain about 29s wrecking them in BGS, but f2ps/vets don't have a problem with wrecking levelers themselves.???
What do the levelers have to say!?
I wouldn't be surprised to see f2p and vets get merged back into the xp off bracket.
