Solid post.
1 and 6 - interesting, I'd get behind it for sure.
4, 5, 14, and 17 - So very yes!
7 - covered by Underworld, (thanks for the info btw,) but I couldn't agree more.
8 - I've ignored the spell until now. I guess I'll have to mess around with it!

9 - I actually enjoy the 4 player group. More characters gets pretty micro in my experience
12 - I can't tell you how often I do that! Very agree!
16 - This would be nice too!
Thanks for putting in the effort for this post.
