More questions...

Big thanks to this community after my 10+ year return (20 year old account), cause I clearly forget a ton.

Anyways, I've geared my 7 hero mesmerway (I still need to perfect the build with some weapons), but here's what I'd like to know:

If I'm vanquishing Ascalon (Hard Mode), what's a good 4 team setup from my heroes?

Where would I look for a group for FoW? Kamadan? LA? Looking to get a new helmet...

Any solo builds from PvX wiki for general farming, or UW farming? Hundred blades works well correct?
