Dungeons, bosses, and raids is what MMO's are all about. Heck, battling dragons and what not is a part of the universe. If you don't want to do them you don't have too, doesn't mean others should miss out due to it.
10-15 man is fine. I would just like larger group content for my guild that is challenging and provides progression. World bosses are always a + as well.
This is sort of off topic, but also related. I was considering buying the Founder pack, but I was wondering if I will also have access to the Dire Wolf pet and Armored horse mount? I know we get exclusive items to just the founders pack but I'd honestly like the horse mount over the spider etc.
