So, everyone basically agrees that starbases are too easy to bypass and do not live up to their intended purpose of defending planets and chokepoints. Some people say they should all move, some say they should all have massive range. I was thinking about the main objection to extended range for the Advent base, being that it would be unbreakable with proper iconus support keeping things at the edge of its higher range. Thinking about that ability gave me the idea; instead of extended weapon range, the base could be given a long range spell that would work kind of like the iconus ability in reverse, slowly pulling enemy ships TOWARD the base, bringing them into it's weapons range and preventing fleets from easily passing the starbase.

I know the spell slots are all used, but it could replace one. My money is on the culture node ability. I know that the whole culture thing is the Advents 'thing', but i think the ability is pretty useless on the starbase. For the purposes of boosting alliegance to your own planets, simple broadcast building are far better. The starbases ability to spread culture seems strictly offensive in it's application IMO, serving to spread culture to enemy planets from non-colonizable nodes. Unfortunately this ability is largely wasted here as well, given that culture is almost useless offensively, since even the most beefed out culture rates fail to lower alleigance on neighboring planets if the enemy has just one broadcast structure.

As for the others, the Vasari base is already mobile and the TEC have no such problem having no abilities like the iconus gaurdian, so the TEC base could be given increased range coupled with a jump inhibitor ability. This would also have the benefit of giving all three races a UNIQUE solution to the problem, instead of adding the same thing to all of them.

Just my 2 cents
