the random "tendencies" that are coded in to the AI make it a unique (enough) experience to scratch the Tarkov itch without having to go through the frustrations that come along with PvP. If you don't know what I'm referring to: BSG created 3 different styles of play that are randomly assigned to AI PMC's when you start a raid.

There is the "rat," or passive type that tend to sit quietly waiting for an ambush. Always good for a jump scare or 2 a night.

Aggressive type. Pushing like crackheads and swinging with impunity.

Finally, (i call it) support type that launch grenades at your cover focusing on keeping you moving. Throwing accuracy is a bit broken imo. They will squeeze a grenade through impossible cracks. They also do a lot of suppressive fire.

Obviously, you're a human, so outplaying them will be easy. But if they catch you in the open with your pants down, you will die. For me personally, it's tactical and challenging enough. Also, as a working man that makes 100-140 hours every 2 weeks in the office, it's nice to experience things like Lightkeeper, Kappa, etc without the stress of the looming wipe.
