From what I have seen so far it looks like the majority of HoT is going to be guild related, as in you need to be in a big guild to do new content. Im in a guild with 2 real life friends, and we built it since day 1, we enjoy doing stuff together and hanging out in our vent while doing it.
But from what I have seen it looks like unless your in a big guild you won’t be able to do much, no guild halls, no raids etc. I know im not alone that many people are in small guilds with family/friends. I really would like to know if we small guilds will be left out? If so I might have to refund my expansion, I still have time.
I know I can join other guilds, however that is not my play style, im a loner when my friends are not on, I enjoy the solo aspect of any MMO I play.
