Not to put you down, or make you feel stupid, but your complaining that a DEFENSIVE titan doesnt do very much damage? The whole point of the ankylon is superior defensive abilities and high survivability. If you want more power was playing loyalist, either spam Kols and marza's and LOTS of kodiaks.
of all the titans ships I have fought (I almost always play as TEC rebel) there was one game where my ragnarov and 6 capitals (3 kols, 2 dunovs, and a marza) plus about 80 other frigs an cruisers took on a single kultorask, and after 8 minutes of battle, I could only break its shields, all the hull damage I did to it was quickly repaired. this may have been a glitch considering other playthroughs the enemy doesnt usually survive long enough to make it to titans and cant compare it to other experiences against it, but if that still rings true in other times of fighting it, then it is overpowered.
back to the main topic, play a rebels, if you want damage boosts, they get savage thrill which gives you a flat 15% damage bonus to all your ships, not to mention the powerhouse titan they get.
