One other change i'd like to see, again concerning Light Carriers. The AI take advantage of the upgrade to them, and spam them in fleet battles. I would either decrease the amount of squads, or improve the Defence ships.
The easy and normal ai's liked to spam light carriers even in vanilla. You get the best experience from this mod by playing against only hard AI's. Anti-fighter frigates have already been given a much faster firing rate to counter the increase in strike craft. It's been perfectly balanced to me so far.
Another point, since we are dealing with more resources and capital ships with three times the health and three times the fire power, hence they are a total force multiplier of X9, so they are much much harder to kill. The oppossing force will suffer higher casualties. If not using cap vs capital ships, this requires a much larger fleet to take out on cap ship.
This is why the placement of fleets and capitals within your empire has become much more strategic. I've already toned down the resources for the next release so capital ships become more rare.
After playing your Mod all weekend I totally agree with Kreyson on the XP of Capital Ships. They level very fast, and spotting a level 10 means nothing.
The reason why they level up so much faster is because their powerful weapons allow them to make more kills in less time. I've already been adjusting the XP requirements for levels.
Well, I enjoy the length of matches on Sins. It takes a while to build up a force, and it takes a while for your force to get crushed. Decreasing build time is one way to do it, or increasing Capital ship building time is another. I personally prefer the latter.
When I first released the mod, I gave out way too many resources. People complained that they were able to spam frigates and made capital ships seem like nothing. Then in the next version I increased the pop cap for capitals and then people said that they could just build fleets of capital ships which made frigates useless and made the game really easy.
In the current beta being tested now, you usually see just 1 or 2 capital ships in a single fleet. They can still obliterate fleets without capital ships, but you'll still get enough time to get reinforcements into the battle.
With the latest economy in the beta, you usually have just enough resources to build or research what you need however you always feel under some economic pressure and thus have the need to expand to other worlds. No longer can you que up 10 research upgrades and still have enough resources leftover to que up an entire fleet.
The pace of the game of the beta feels a lot slower than the current release but believe me, it's way more balanced now.
