I played around with it some in single player. The ease with with the Pirates can be knocked out might be problematic.

titan farm I call it now.

Yes, it can but I don't have a problem with that.  Later in the game I was in an enemy territory and he had his Starbase leveled up a few levels.  and I had a lot of trouble trying to take out the Starbase with just the Titan.  According to Stardock, Titan should be able to take out a Starbase.  not so true.

Again, I was able to rid me of the Pirate filth, but it was not easy by no means.  the Pirates had a lot of ships there that were causing all kinds of havoc.

My opinion, the titan is what its supposed to be, and I don't feel that it needs to be fixed.  leave it as is.

not the titan but the pirate well could get a further upgrade else it will be a valid tactic to farm the pirate well.

I personally parked my titan with hold position at the edge of the well and just farmed the spawning fleets for a while...

Ill add that the Pirates can be naturalized pretty quickly and not by using a Titan.  Build a Novalith Cannon and blast the Pirate Base. no more threat. Pirates naturalized.  And I have seen this done first hand so yes it is possible.
