I had a 10 day trial a while back and I couldn't get past the Garrison content. I mean i really disliked them, hate is the proper word. I like crafting, mining, raiding and 5 mans typically. I wanted to get back into the harder raiding (now Mythic) and that seems like it fine (really do not know for sure but looks to be good).
Anyway, I came to a screeching halt with Garrisons. Perhaps I should have investigated further but I was totally turned off by them. The question is, looking at what I like to do above....can I avoid Garrisons entirely if i wanted to, with out that getting in the way of what i want to accomplish above?
