I really don't understand all the complains of "The A.I. sucks" that I've been reading. Obviously they are made to be stupid. As far as I can tell, what you've described here is EXACTLY how Respawn meant for the game to be played, and I think it works well within that framework. I can't even imagine the hate this game would get if there were even semi-competent bots running around slaughtering people.
Oh certainly, I can see the deliberate design mechanisms everywhere. What I think though is that it's boring design. My preference would be to remove them, up the regular player count to 8 v 8 (so up to 32 if you count 16 players + 16 titan A.I.), and then have pilot kills cost ever so slightly more titanfall timer reduction points. This way you're always facing actual combatants, and you're not just feeling completely glazed over by the repetitive and garbage gameplay nature of the essentially do-nothing A.I.
I mean the problem seems to me just that it isn't very fun as a mechanic. Every time I kill a bot in the game, it just feels like I've wasted a second doing something inherently stupid. Might as well be kicking the side of a street sign for all it matters from a skill perspective. I do not enjoy gameplay where I have to contribute absolutely nothing of my acquired skill sets to accomplish.
