as i said only the vasari would be able to move their bases.

I did not see this. However, I think that all factions would likely develop this kind of capability. Think about it for a moment; the TEC build big, robust, sturdy-hulled ships, that tend to be very rugged and usually multi-purposed. Seeing as how all we have to go on is the game for quite a bit of background, I think it's a testament to TEC (or rather Trade Order) design versatility and durability that converted starliners and bulk freighters can stand toe-to-toe with dedicated warships.

In the case of the Advent, I'd wager that the Advent Transcencia Starbase is mostly Psintegrat controlled; there is likely to be very little crew. As such, it's likely the lowest-massing (and thus easiest-to-move) SB. That's all background-wise, though.

You botch your own saying through the implementation of your naff spelling and grammar skills.

You realize he more or less asked for it.

the thing to support me on this, is the fact that the vasari base already has an engine.  the other bases are designed to defend a grav well.  they dont need to move their bases.  of course if you want to you would need to develop the tech and it would never be as good as the vasari who would have designed their base for said movement.  in fact for the other two factions i would say you would need to use up an upgrade to make it moveable.  one at the 2700 credit cost. 

the vasari on the other hand should get a little faster with experience.

This is a better idea than building your starbase in a hostile grav well and upgrading it there, build it in an adjacent neutral well and tow it in, or better yet, use the Marauder to phase link one of your core planets to the enemy homeworld, instant overwhelming firepower from the starbase AND titan wherever you want... I'm switching to Vasari if they do this
