I am not sure if I have seen this setup mentioned

Main -> RAF A --> RAF B
new toon LvL 60 new toon

I want to level up a new toon (to say 30) on my main account and use a poor equiped lvl 60 druid on the linked RAF account. So in order for my new toon on my main to get the triple XPs I need another RAF toon right? Can the 2nd RAF account linked to my 1st RAF account (RAF B above) achieve that? Will it matter if the last RAF account has just the 10 day trial access?
