GW2 and HoT: Open World Events
I regards to world bosses, they’ve always been pretty big. However I feel there’s only a select few which are interesting. Claw of jormag, tequatl, triple trouble, and shatter are pretty fun, the rest are sort of blown up because of the number of people who show up to them. Heart of thorns meta events are pretty fun, although challenging for a few. However, it seems like you’re familiar with mmos in general and will be fine. The quest lines are actually pretty cute if you look at them outside of an objective view. For example there’s a skritt that falls in love with an exalted in aric basin and try your best to help her piece him back together so he’ll love her. HOTS is full of events and action, but it’s limited to about 3 maps currently. However I’d argue they’re the size of 6 general core tyria maps. I’d suggest using the LFG tool if you plan on trying to do any big events. For core tyria there’s SW which is always active and world boss train. None of these require a guild, but being part of one wouldn’t hurt.
