Her most interesting aspect is her new Skill 2:
Formation Enhancement. Any MGs and SGs on her tiles receive 10 points of Movement Speed (this does not include herself). Once Type 80 activates her Skill 1, she also grants 20% Damage to dolls on her tiles, and reloading also gives a 10 HP shield.
Being able to rapidly move your shotguns and give them shields when reloading is a nice novelty, but does not have much application overall. Besides this Skill 2, she also gets the usual stat bonuses, tile improvements, and her Skill 1 buff adds a passive effect where the first shot against a new target deals 50% increased damage.
Overall though, despite some interesting potential, Type 80 will be a skip for most players. She doesn’t offer much substantial compared to stronger MGs that don’t need MODs. However, the novelty from her
MOD2 can still be useful on occasion, so some may enjoy what she offers.
The Set brings Type80 up from being more of a support MG to being able to actually deal some damage herself in shorter fights. It does not really help her out in longer fights outside of now being able to actually equip her SPEQs. Why they decided to give her a 200% AP buff during her Skill instead of just fixing her Ammo SPEQ to be a SLAP like every other MG only Mica knows.
Overall, this makes Type80 capable of dealing good damage in short fights, but still more of a support MG otherwise.
