2. Titans are defenitley not OP.
They are actually rather weak, especially to the TEC. The Vasari have the hardest time destroying them since their fleets don't usually have as many starfighters as the other races. With that said, the easiest way to defeat a titan with the vasari once vasari become playable will probably be to mob it with kortuls or to use bomber swarms.
The advent have a somewhat easier time of it. The key to killing titans as advent is to never, ever get in close. Use massive numbers of fighters to kill them.
Sometimes, though, fighting them close in is unavoidable. In that case, i would make sure to have many guardians protecting your fleet. Use animosity on the radiance to absorb its fire. You NEED to use multiple radiances for this, as a titan will rape a single one on its own. Switch them off to spread out the damage.
The TEC, however, have the most effective technique for dealing with titans. (in my opinion. It is slightly more dangerous than bomber spamming but far quicker.) What you need is two or more high level dunovs and several kols. The tactic is pretty much to totally decimate the titan using GRG (Gauss Rail Gun). For this tactic you really need high level capital ships. And not just kols and dunovs! Only an idiot would send in their titan unsupported. It's very very useful to have two marzas with missile swarm and radiation bomb leveled up to destroy the titans attendant hoshikos and frigates. Also throw in an akkan to keep shooting ions at the titan to control its special abilities.
All of that is not really necessary (you could destroy alevel one titan with probably just two kols) But to really roll over titans, you need either a good assortment of capital ships or MASSIVE numbers of bombers.
Also, corvette-class ships are effective against titans, but i don't like using them since i have a sense of honor.
So, everyone can bomber swarm (with Advent being the best at it). Use animosity effectively in a pinch. Corvette spam. Use GRG with dunovs as TEC.
Kortul mobbing will probably be effective once the Vasari come out of hiding.
TEC have the fastest way of killing them.
