I reccomand to use ranodmbuddy, but there is also a builtin profile that I used many months without anybans and a greate NPH and you could also use it when you are already 600 herb and mining
and also i remember using that profile..it toke me to a HERBALIST trainer and am like wtf i do not have herbalism. i just have Mining and JC so i uncheck herb and just mining but the problem is i never used mixed mode / random buddy it just toke me to the herbalist trainer in kun-lai which were i was near kun-lai
