Also Conan: trade ports dont give dimishing returns.
6 Trade ports on one planet give exactly 6 times the amount of a single trade port.
They can if your longest trade lane isn't big enough - or you don't have enough trade port's at other planets to trade with. Which is usually not a problem if you have the capital and can afford to put 6 around one planet. If you own like 3 planets in the corner of the map and you decide to get rich quick and build 6 trade ports on one planet... won't work, no.
Longest trade lane length gives your trade port's a cap - and you need 6 trade ports on your other planets to get the benefit of that. 6 trade port's on one planet, 0 on others means NO TRADING. No benefit. 3 on one and 3 at an another... thats viable though.
A well planned and flawlessly executed RA by three players could have had at least 3000 fleet supply ready at the one hour mark storming your system...
No amount of support cruisers would have helped.
I'm very sorry but if your opponents have gone un-harassed with enough time and money to get up to Dark Armada in the first hour, especially as Vasari who are lacking in logistics slots to begin with, sacrificing all those slots for trade ports, refieries and factories for nine empire research buildings... Which is a huge financial investment too. Then you suck, theres no other way around it. No 'flawlessly executed' or 'properly planned' on their part about it. You just suck. End of story.
Even just getting Insurgency tends to REALLY hurt a RA based Vasari player, since 10 of his tactical slots at every planet are taken up by phase gates. RA is FAR FAR FAR from being a 'end all, be all' strategy.
It doesn't build anti-fighter, siege frigates OR subverters or overseers. It uses up ALL your supply cap. It is an ungodly whore to replace capital ships or adapt your fleet with RA on autocast. HAve to go, scuttle your ships for supply cap, hope no RA comes while your going back to your planet and queuing up your capships... and to top it all off, for ENDGAME they don't even BUILD ships very quickly. On small maps, your better off sticking to factories. MUCH better off. You need a certain critical mass # of planets WITH Phase Stabilizers (expensive and takes 10 tac slots) to even make RA viable to begin with.
Whereas the TEC and Advent help proportionally well - on any map. Each strategy and research has a different positive and negative.
