3 man boxing in WoW Classic suggestions

[Tazeon]

let you inspired from this thread
https://www.dual-boxing.com/threads/57142-2-box-farming
there we discussed allready what jak3676 said, there is not enough value in dual/tripple boxing

[EDIT] small correction: with tripple boxing you can do DM East Jumpruns with tank, healer, dd and covering all 3 professions (herbalism, mining, enchanting)

if your main goal is only doing quests, also with lev60 then many compositions are viable.
2x mages for damage are the best and easiest(I dont recommend more then 1 melee or hunters as a starter)
3rd charakter should be a healer (paladin, druid have the possibility to tank, priest is strong if you want aoe grind with stamina buff and shield)

I suggest to start with 5 charakters.
isboxer and retail wow you can test for some days, and learn how to use the software
then I would try it for 1 month, if you dont like it you can switch to 3,2 or 1 account back.

as allready mentioned:
all software are easy to handle compared to the past
but it will take time to master it and you will learn it by doing
you dont need all functions from the start.
