I've watched quite a few youtube channels about this game now to make sure I'm not, hopefully, just being stupid. :p But the Ai is really getting frustrating in combat.
Some examples: My carriers (Moras, equipped with only PD weapons) charge in front of my cruisers, both getting themselves killed, and blocking the cruisers from firing.
Same with the Gryphons. I removed all but the long range missiles and point defense, and they charge in point blank and use their PD weapons, even against bases.
I have experimented with issued defend location commands, but the 'tether' seems to be merely a suggestion to the AI, and they will literally wander 1/3 of the way across the space area to attack something they could hit with their Squalls from a safe distance. Rally seems to work slightly better (shorter tether?), but my carriers and missile cruisers will often then sit there and not fire unless given specific targets. That wouldn't be so bad, but with limited command points (not as much an issue any more with Ops Center on my flagship) it can affect the outcome of a big battle.
I know it's not just me, because I watch some of the videos and the players there are often yelling (rather amusingly, I may add) at the AI. Destroyers charging in and getting themselves killed when there's a Dominator or Eagle that could have easily soaked that damage and the DD was assigned as escort....
I'm trying to find AI friendly builds, maybe to help, but nothing seems to significantly affect the behavior of my ships. My fleet doctrine is set to steady, all my officers except one are steady (and the other is cautious, trying to keep at least one of my carriers safe). I can take screenshots, if it helps.
