For how long?just doin 5 man mop heroics and never got a ban ...
doin it about 12-18h per day
Nah stay away from MoP dungeons. Blizzard has an eye on them too.
Beter some solo profile, but avoid solo dungeon farming too.
You only do 5 man dungeons MoP if you can accept that ban will come. You can usually use the accounts for 7 to 10 days top.
