Hi,

Can there be added an option at the beginning of the game of not playing with Titans. I know it is the point of the Rebellion, but sometimes I do not want to rush and be the first one to build a Titan. When they are present it seems like the whole game revolves around them. 
And even with a higher construction cost I still think they are too powerful, especially when leveled up. And leveling up does not take too much effort since each Titan is so powerful that I can send it to a pirate base, supported by Hoshiko and wait till it exterminates everything there and leaves the base reaching level 2 or 3. I suggest either making them weaker in general or making them vulnerable to strike craft. This way there will be a point in building costly carriers.

And what is the point of corvettes except for the battle looking more alive with corvettes rushing towards the enemy ships and being almost instantly killed? I'd say, give them a role, such as Titan killer or allow them to interfere with long range frigates' missiles and make them miss or do something else useful.
