About the same here, the AI never sends more than 20-40 frigates at best (no capital ships) and no matter if it's rebels or loyalists they tortoise a lot. I had randomized AI behaviour so it may be that both AIs were defensive ones. The victory conditions were last flagship and last capital planet (both activated)
This was in a big map, (60-80 planets, 5 stars, 3 players myself a rebel tec, the other two rebel and loyalist tec).
Also, I've noticed the rebels only send pirate ships after a while (20-40, no capital ships) and don't get any more planets after researching the Truce amongst Rogues, which i guess is the intended behaviour but leaves them really crippled with only a few planets (and rebel fleets and pirate fleets aren't big enough to compensate and become a threat).
The loyalist did take a few more planets, but at a very low rate and only send a few ships (15-20, again no capital ships) to attack. Also, their fleet remains at their core planets so their 'outer rim' planets become quite easy to take. Also, when they do defend their fleet is scattered around several planets, so I pretty much wiped them out without losing a ship. Once I got to their capital planet they tried to defend but left their titan and part of their fleet away with their flagship (which I hadn't yet found) so it was easy as pie to take their capital planet.
I've noticed that while they do build titan ships, they only use them to defend their flagship or capital planet so their titan doesn't level up as much as mine and can be taken out quickly by my fleet.
In trinity, this map would take me 10+ hours to win and i'd quite likely lose but in this case I'm about to win after 2:30 hours of game.
Other than the AI, I haven't had any crashes, the game runs smoother than in diplomacy even in large battles and I'm quite satisfied with the new factions.
I hope this helps out.
