Yeah, I could've seen going 20 hoshikos where he went 30 instead. I'd have used the extra supply for carriers or LRMs, probably. That fleet might have worked wonders against a Vasari player with no decent repair ability (curious that he's missing a Skiranta), but a TEC player with less hoshis and some actual LRM support might've rearranged that fight. But honestly...why is anyone making a fleet with more than 2 Ceilos? Especially one that small?
I generally take TEC due to balanced SC design (Advent get higher numbers but they're weaker, and Vasari have much stronger but get less per group), faster trade research, cheap ships, and probably the best over-all capital ships in my opinion. When I say the "best over-all" I mean...I'm willing to use 4 of the 5 cap-ship types of TEC in any game. I don't really use Sovas unless I'm screwing around. Two Akkans almost negate the need for a colony frigate (barring the neutral miners, of course) and work a lot better. The Targetting uplink is a decent passive ability that lets your fleet get off a few shots before theirs comes in range. The Ion Bolt can cause problems for Marzas attempting MB. Marzas...need I say more? Kols...flak burst, oh so much. And a pair of Dunovs with shield restore keep a fleet alive (and with their ult. ability, Flux field, can make hoshikos and Kols that much more powerful). And civilian tree techs? Give me Industrial Juggernaut and Pervasive Economy FTW.
The Advent and Vasari have less abilities that I want as capital ships go. The Vasari's mobility is definitely something I always consider, but the cost of that mobility is also something I consider. The Advent are the hardest for me to play just because the sheer cost of their empire and their "culture is everything" focus kind of falters due to culture's simplicity. If culture could give you more rewards (such as planets joining you without needing a severe carpet bombing), then it might make more sense.
