Overview
MK3A1 is a SG who summons drones.
MK3A1’s drones can help tank if her Armor is sufficient, but if it is sufficient, you likely don’t need the drones, making a bit of a Catch-22 here, considering Flash Ammo exists. Her tiles for MGs aren’t terrible, and the Evasion doesn’t really matter (even if applied to herself). The only real application ends up being that the final drone can snapshot SPAS-15’s 40 second Armor buff, and this is a niche interaction even for Ranking.
Overall, MK3A1 ends up being more useful for CE stacking for Friend Echelons than any other content. As there are plenty of far better SGs available, she is copium at best.
