I'm about to hightail it out of there when I noticed something interesting. After a single pass all of my opponents strike craft disappeared. (I usually set an equal ratio of bombers and fighters after mid game) My computer opponent was terran. I looked at the target for my bombers and noticed I had taken a nice chunk of shield so I thought maybe I could take down one of his capital ships before mine got destroyed and I figured I would be able to run if things got dicey. (Yes, there were flak frigates with the fleet)
This does sound pretty strange. Unless your fighters killed all of the enemy strikecraft, they shouldn't just disappear. The only other reason they would disappear would be if the AI had decided to send its fleet someplace else and they were preparing to jump, in which case the strikecraft return to their host. It's possible that if you were using Telekinetic Push (from the Halcyon) that you might have killed all the strikecraft.
So I stayed getting ready to split on a moments notice. I needn't have bothered. I wiped out every single ship and they didn't even get past my shields.
2 enemy capital ships, 30 frigates, and 3 carriers should have taken down your two capital ships. Did you actually see the enemy ships die or is it possible that that fleet just jumped out of the gravity well? Capital ships really don't have much firepower, especially a Progenitor and Halcyon. (The only two that do have a lot of firepower are a Level 6 Marza (missile barrage) and a Level 6 Radiance (cleansing brilliance).)
If you actually killed them all with just those two capital ships, then I would chalk it up to the idiocy of the AI. Real (human) opponents (in online multiplayer) would have knocked your capital ships down quickly, especially if they were Vasari. You would have either been hit with nanites coming from an Evacuator capital ship and then focus-fired on with upgraded phase missiles or you would have been attacked by bomber spam coming from Skinatra carrier capital ships combined with upgraded phase missiles.
Since the flak frigates go after fighters before targeting bombers, they weren't really even an issue. I just watched amazed as the first capital ship went down without even 10% of my shields being gone. I didn't use any fancy maneuvering, I duked it out toe to toe. Sure I had a lvl 9 and a lvl 8 vs a lvl 7 and 2 lvl 6, but even so that's ridiculous... 2 capital ships wiping out 3 so handily that they also obliterated 30 frigates without even having their shields punched through? I then looked around these forums and saw people touting phase missles as uber and wonderful...
Maybe you did kill it all. That just shows you how incompetent the AI is.
So I looked at the vas tech tree.
Phase missles are only capable of doing 30% phase damage. That makes upgrading phase missles worse than useless! Sure shooting through shields sounds great you get to damage the hull directly. This is good right? WRONG (maybe Im pointing out something someone has already stated so forgive me if I'm repeating). When you fire at the shield, you shoot only at the shield. So at this period of time only the shield regeneration kicks in. During that time the hull regen is inactive.
The phase missiles AVOID the shield mitigation. You need to learn what shield mitigation is about.
When a shot hits the shields, 100% of its damage rating is not done to the shields. A percentage of that damage is mitigated by the "shield mitigation". So if a missile does say 10 points of damage and the shield mitigation is 40%, it really only knocks 6 points of damage off of the shields. Shield mitigation increases as a ship takes more and more damage. So at 57% only 43% of the damage is being done.
Phase missiles avoid the shield mitigation--a phase missile that does 10 points of damage avoids the 57% mitigation and does a full 100% 10 points of damage to the hull. It's like doubling the amount of damage that the missile does.
Advent ships have weak hulls relative to the other races which is why phase missiles are such a good way to counter them. Oftentimes (in online multiplayer) you will see Advent ships die while they still have 50% of their shields left because fully upgraded phase missiles destroyed the hull. If you are playing against a Vasari opponent in online multiplayer, you would thus want to seriously consider upgrading your ships' hulls and perhaps armor (especially if it's cheap, like for the TEC).
Also I have taken the halcyon carrier at level 1 against nearly every type of other capital ship 1vs1 and it seems to win against everything.
That is strange. I wouldn't think a Halcyon (which has a weak hull) would stack up against other capital ships. Maybe if you gave it bombers it could do that. I think that an Evacuator would easily knock down a Halcyon with Nanites.
Anyway, welcome to the Sins community. I hope that you'll consider coming to play it online after you've played it for a couple weeks and learned the game. You can play comp stomps (humans v. AI) and games against actual human opponents. It's a lot of fun and many people have enjoyed many epic 4v4 and 5v5 games. It doesn't take as long to play online as you might think, just 1-2 hours. (In a 4v4 or 5v5 you don't have to kill all of the other players yourself, you only really have to kill one of them and normally the players on the losing team see the writing on the wall and surrender rather than make the winning team go through the boring motions of mopping it up.)
