No, it's not early, between tribble and private matches, people have done a lot of testing.
Interesting, I've never tried the security kit before.
People are all over about season 4. Some swear a kit or weapon is useless while others laud the same one as OP and their favorite. All I know is that on Otha we are having a blast, and people are using all types of guns and getting kills. Shanty Town too. I see Tac shotgunners failing to instakill, Sci medics dieing while self healing, premades taking deaths, all much better than before.
We just need a little tweaking as they are doing.
