The only way the corvette could be more OP is to give the little sob fighters of its own, then it will, as it's done to Heavy/Light/AntiFighter, make also the Carrier frigate not worth building.
You have to get at least 5 military labs to develop your fleet. You must lay out lots of credits, metal, and crystal, then work up your fleet supply. Finally, you build up your fleet carefully choosing what you think is the ideal loadout. 1-2 capitals leveled up to at least 3. Frigs/Cruisers have all their abilities. Ready to go.
But the other player is Tech Loyalist, but it doesn't matter, who built up their economy with 3-4 civilian labs and 2 military lab and you are screwed without realizing it while your titan builds slowly and expensively. Why are you screwed? It is elementary my dear Watson. This player is corvette spamming and with an average supply of 3 and low cost has 70 of the little bastards just waiting. 70 of these monsters are gonna barrel your first capital with 2100 raw damage on the first inbound run. But wait... your pain isn't over yet because as they race off giggling they fire a parting shot each for another 1750 raw damage. If you had some fighters, they aren't in great shape either.
So, careful player with mixed fleet, titan in the works, 2 capitals doing nifty... 1 just got pounded with 3850 damage on first run. Mitigation aside, on the next pass he nails the other capital, then works through your fleet so the mitigation drops on that first capital -then he pounds it and cycles through the targets.
How to avoid being screwed? Don't build anything except corvettes you silly willy.
How StarClad can make the game fun and not Corvettes of a Solar Empire:
Rescale 3x, make them fit between light and heavy.
Boost cost to between light and heavy cruiser, bump armor a tiny bit, boost Hull/Shields 3.5x, change back weapon to light and able to fire on fighters.
Boost Anti-Titan ability % values 4x to reflect that it now takes 1 ships to do what 4 did previously.
Require Tier 3 research instead of Tier 0 for corvette unlock.
These are anti-titan, so let players get their conventional fleets out and play the damn game as they have all through Trinity, even get their titan out and having some fun. Then, bring out the Corvettes. There is no reason to have such a powerful and spammable ship out so early.
