What people like me have been trying to say, I have 3 accounts and can do many things people think I can’t. The same applies to people with around 10 accounts.
If they follow the rules there has been a change in the farming you’re talking about though, They can’t tag everything on more than one character at the same time, Which means you have more chance of beating them at a tag, They as effective as a boomkin in a group competing with you for tags on mobs.
There is the hardware input argument though, That Blizzard has left a huge debate on. Let’s just say that’s banned for the sake of our posts.
Boomkins have always been used in groups to beat people to tags, me and my friends used to use one for Warbringers in mop and to farm treasures in vale with pots of gold on. If a “multiboxer” is solo tagging with one boomkin and looting on 4 other characters. It doens’t really effect you different than a group doing it with a boomkin, Which will defo be a thing in shadowlands too.
However prepare to bots galore, not multiboxers but bots, Who know they will be banned and don’t care, We’ve not seen anything yet, Quote me later.
