Hello, I created a couple of alts on the same account as my main, but I'd like to have them on another account just to be able to enchant their items with my main and to trade items faster inbetween them. I thought players were only allowed to have one account, but after reading the multiboxing rules, I now understand that we can have two characters in a main city for trading, crafting, etc. I couldn't find any post regarding this question or any info saying that this can or can not be done, that's why I'm asking ^^

Can we talk about this? I would love to use some legion models on vanilla, but I am curious of why we're not allowed to use custom models. (I'm talking about additional MPQ files that change player models and mobs.) Why is this a thing?
