Are you kidding, I thought this would be best for multiplayer. Finally there will be a unit that can bring a game to a quick end if the team that was winning brings it out, and if the losers rush to get it the other team should have a sufficiently large fleet advantage to win anyways.
When a team knows its losing, it will tend to quit by itself, however this will not stop the small minority of captain picards and captain kirks running around the map with one capital ship to make the game longer.
I don't think introducing a titan capital ship to multiplayer will help, as many people who play online tend to exploit imbalances. If the titan ship does cause imbalance, then this will only just annoy people and will force people to leave the game. We have already seen this happen with the overpowered illumantor bug and the other imbalances effecting the game previously.
Screw multiplayer . I don't want my singleplayer experience gimped because of the whining of the MP crowd.
I gave suggestions for both single player and multiplayer, single player can have the titan capital ship, but I feel another way to gain the titan capital ship online is needed so that the game doesn't become an automatically loss for the team which doesn't have the titan battleship.
The titan battleship can be seen as an crash landed alien ship, which needs repairing. This kind of multiplayer scenario can increase the enjoyment and strategy of both the mulitplayer and single player community. We all know by exploring planets you find artifacts such as 'phase drive' or 'archive' etc. This can be found and sent to the crash site to repair the damage alien titan ship.
