As said. Low tier.
I'll tell you this. In in 120M-140M bracket. We also have 7 wins in a row. The last time we faced terrirory of 25 NS, we finished it in 30 mins. A record for us, for sure. Do you even realize how absurd that is?
NS are amazing offensively since they can counter CLS and jRey teams.
NS are horrible defense at high tier since they have huge counter - troopers. All guild almost demands troopers because of DS TB. So they have 50 teams that can counter NS.
Cls for example, is great defense. Why? Because people put his counters (rex, GK Zarris, jRey, NS) on defense. And then, they can't deal with him. Also, same for jRey teams.
I split my NS to 2 teams : aco+zom counter cls, MT daka ventress counter jrey. Instead of one, very weak defensive team (cause my enemies have troopers), I have 2 offensive teams that win better power and better zeta+gear teams. This is making the most out of your roster. This is how we beat guilds with 10M more GP - we do this tactical stuff, they do mistakes like NS terrirories.
And obviously, troopers are bad defense, and almost sure they are on offense.
So, with no disrespect and I don't wish to sound condescending, but you are playing vs low tier guilds that do "no brainers" stuff that cause them to lose vs NS.
Also, your advice might be better than mine for OP if he's in low tier guilds aswell.
