After 1.0.0.95 Update, built bases still capture very quickly. I built-up a coastal base with almost all of the de-facto supply points, while somebody built many (thousands) of barricades.
A three to four crew of enemy (could have been six to eight enemy, but no more) quickly walked into camp and almost took the camp very easily, without destroying any of the two antenna towers.
The 1.0.0.95 update noted built-up camps are more difficult to capture. I, so far, experienced no change in capture time. All of the time spent building seemed futile efforts.
