I know bro. I have some NS+GK arena teams in my shard. Once they are arena modded, with highly geared zombie, and have Zetas on unique of MT Av and Leadership... This is whole different story. But this is not ordinary NS team. This is arena team that will require arena team to beat.
Hardly the case in the post I believe. The general talk here is towards lower geared NS or lower modding and how they perform on def vs off.
If I find a team like this in TW, I'll leave it for someone else, or use a team to kill GK and then go on it, since my troopers can't beat it, and my arena team guys is split into defense. Don't think I'll see terrirory with 25 of those specific teams, and if those team will become real meta, people will be prepared to beat it. If I would have that kind of power on my NS, I'd put on defense aswell.
My point is - these teams aren't "NS teams" that should get the treatment of troopers/other counters to NS, they are different level - "arena teams" , and should treated as such. Chaze + Strong CLS / God-like troopers.
