Well, they already reduced the number of super weapons you could build to 4 in Rebellion to try and deal with the problem. A lot of players thought this was a bit extreme though, especially as the TEC Loyalists needed them so much,  and that as a player its fun to use swarms of them. Thus in the next patch, the number of superweapons you can build will be based on the size of your Empire. Small Empires will only be able to field 1 or 2, large ones could build more than 4.

FYI to deal with Novalith attacks, build starbases on your important planets, and build the axillary government or equivalent upgrade, and you will not lose your planets to bombardment, including Novaliths. TEC shield generators can also reduce the damage and deaths the Novalith inflicts, by up to 70% full upgraded.

Also FYI the AI did use superweapons in the final patches of Diplomacy, without any limit to how many they could build. Also the harder AIs get a economic advantage, and Cruel+ AI get faster research, plus perhaps other noncombat benefits, allowing them to get superweapons faster and in larger quantities. Even if you can beat those AIs I'd say its smarter to stick with unfair AI, the harder ones are indeed not as fun to play against because its not even close to a fair fight. Try doing more challenging scenarios or give yourself restrictions (I.e. no building starbases, which the AIs suck against) to make the weaker AIs more fun. Or there's also online play if you want a real, smarter challenge.

Turtling early is a bad idea in Sins for everyone, even the TL. They need a large economy if you are going to support lots of starbases and Novaliths, and that means planets and trade chains. What the TL should do is get the same sized Empire as everyone else early, then turtle down and go for Novaliths to try and win the war of attrition.

That said, Novalith Deregulation will allow the TL to build twice as many Novaliths as an equivalent sized Empire, so they do not need a larger Empire to out superweapon the competition.

I didn't know there was already a limit, I was just getting really mad that I waswaist deep in hoshikos and percheons that I couldn't pull ouy long enough to build star bases, and I kinda forgot about the sheilds. Another thing I've noticed is the seemingly unending use of one type of ship per faction/race AI. The loyalist I fought yesterday used light carriers, repairs and the Marza, which in my opinion is the second worst TEC Cap shit, only beating the new ship whos class I have yet to devote to memory.

Hey it's like we're playing vanilla all over again!

[EDIT: man, it's late.  took me a minute after posting to remember superweapons were in vanilla]

You speak as if this was mere theory. Go read the patch notes, that's what's in stock for the TL come tuesday.

I like the Kol though, they seem to be able to handle swarms of heavy crusiers with some success, this being said I produce two of each then three Kol and three Sova. As for the Marza maybe I never noticed its use, but I always keep at least one in fleet. The Dunov has started to grow on me, I never found it combat worthy when placed next to my favorit cap the Akkan who broad sides can handle groupings of frigates, but the Dunov's sheild recharge makes it useful in the large fleet engagements that I always seem to jump into.
