Darkstar Fortress impossible to capture?

Does anyone else feel that the fortress in Skirmish at Darkstar impossible to capture? i don’t think i have ever seen it switch hands once it is captured and if it has switched i definitly have never seen it switch a second time in the same game. While this isn’t what always determines the match i feel like it causes frustration and reduces the willingness to attack the fortress therefore taking something away from the map.

Possible solutions:
Reduce capture time
make defending team spawn futher away
eliminate the marines (my favorite solution)

What do you guys think?

I have a few times actually, it’s just like the stormbreak or whatever it is called. Doesn’t happen often though.
