GMS leaving asian content aside?

It always better to have it, than not. Every area can be boring for some people. This a reason to have more towns. I personally hate Ludibrium

Siam looks awesome, i don't know anything about quests so who knows maybe they are interesting too. Boss there is funny too, it has very nice skill animations and ... I love monkeys

Also WT area are good because they are accessible from almost all towns. It's helpful for fast meeting

I am still waiting for Big World Tour Patch which will add Shanghai, Formosa and Floating Market.
