A lot of you are complaining about the bots, so I wanted to address that. If you are complaining about the bots I can only assume that you have not reached level 15. From level 1 through level 15 I played only on normal. And let me just say that for the most part the AI truly was unbelievably stupid. It did not buff, would take seconds before shooting, would stand still. Yes, it would do all of those. But as soon as I hit level 15 everything changed. Its almost as if the AI got pissed at me!! Those bastards all of a sudden became killing machines, shooting on sight and extremely accurate. And im pretty sure that they started constantly using kevlar vest because my hits where no longer as damaging. And even more something that really surprised me, was the places where they started placing their turrets, 2 and 3 at a time!
Bottom line, I feel that those of you complaining about AI should maybe play more and wait till you hit level 15. If by then you still feel the AI isn't good enough then try on hard.
Wait, are you talking about enemy AI or teammate AI?
Because the enemy AI bots are EVIL! They turn so fast and slide/melee me quickly and are just RELENTLESS in their pursuit and tend to camp at objectives. They also
know how to cover each other very well and can complete the objectives with little problems.
Now, the teammate AI.....at least, on Normal, are beyond moronic. There are only maybe 4 semi-competent-ish bots, but they tend to get killed because the rest of the team is not helping with cover. They tend to get a little derpy in some missions and are obsessed with Command Posts and secondary missions. Also, Medic AI love to rush into gunfire and then die three feet in front of your own dying body, lol!
EDIT: Shinigami, Please tell me that you were talking about teammate AI!
