I think the tech-labs-in-capships is OP as is. It is a comparatively small investment which gives an instant super-up on researchable tech level.
I think it should be 2 techs, one for civilian an another for military tech labs, and each one should be researchable 8 or 4 times, to unlock the ship labs one or two at a time. That would make it more progressive and increase its cost.
The VL Titan should get a turning speed bonus on casting the MPJ, and/or perhaps a better turning speed overall. The #1 tactic is to jump behind the enemy fleet to use the maw, but it would have to turn 180 degrees first. It could be fast but short-lived, like 500% boost for 5 seconds or something.
AI is also derpy at times. I started invading the planets of one AI one by one, and nary a fleet showed up to try to block me. Even when I was attacking its capital planet (with the capital victory condition on), no one showed up to deter my advancement. When I went to its remaining systems, most were littered with Titan foundries, but no Titan in sight.
It still consistently underestimates the power necessary to bring down a starbase too. Jumping orkies makes it much more important for the AI to be smart enough to know how to stop it, or the challenge is spoiled.
I still saw several cases of ships idling, both mine and enemies, especially fighters and corvettes, in the midst of combat, when auto targeting. Manually setting targets unfreeze the ships.
Calling the targeting attention span derpy is an offense to derps... (Titan about to be destroyed with less than 500 health, fleet sees a lone scout *OOOOOHHHH SMTHG SHINY LEDZ CHASE DAT BUTRFLY*)
I have already commented in other threads, but I think the Vasari Rebels should have some good synergistic abilities with other races, plus some way of getting reinforcements of other races, or even building their ships. I also think there should be a 'shoots effects to adjacent gravity wells' theme in their structure skills (weapon jammer, phase inhibitor, repair bay).
The jumping Orkulus should have some deterrent, like some after-jump cooldown of at least a minute before it starts moving and shooting, and it fits better the VL theme than VR.
