I agree that regulator Kylo should be in place FOSFTP. For NS team, think about using Spirit instead of Acolyte. As for defense, zetas make a big difference. If you have the two Kylo's zetaed, they can be quite a pain to take down for who you would be facing in Div 10. If you have a fast NS team, especially a fast zombie, they can be quite a pain to face as well. Your best bet is try to get both teams up and running and put them in different zones. A lot of GA is about balance. You want good defense, but also need teams for offense. Learn all the counter teams. Putting Geos on defense is a good strategy, but also assume your opponent is going to do the same.
I'm in Div 1, so I have to field eight defensive teams. I generally pair a strong team with an average team in each zone. I stick Geos and JKR in the back, hoping opponents will blow their counter teams on my front four. It is a mixed bag in terms of results, there will always be someone out there with a better roster than yours.
