The bots are messed up. I've seen BOT Cheetah's lay 6 mines at a time. No human will ever be as efective at placing mines as a bot. They have broken abilities with Javs/Helix/Orion mark (anything with auto-targeting enhanced abilities).
I don't think these things will be officially fixed until something bigger is broken, unfortunately.
the cheetha bots have ability reload implants of legendary or epic which maxed out so they can drop out the 3 mines in one time which is very annoying coz u r dying without any reason u can't even step in any of the map and if u step the mech died instant coz of those mines activated at same time 😭😭
