I, still think the capture points should be easily captured, rewarding ships that are in the capturing zone. This is both advantagous and disadvantagous for all ships current.
Slow tanky or hard hitting ships can hold the point, while fast ships can get back into the point easily.
Because i played a game of 3v3 crazy king where the enemy team had 2 squids, they always came back to block the points because the spawns were so close, the ships were fast and the capturing was too slow to win over with. So, imo the most simple solution is much quicker capture time.
Goio suffers alot from using standard gamey game mode type modes. Things like, capturing a capture point with slow flying bulky ships is just difficult. It being crazy king should in itself be enough that the one who is on the point keeps the point. Anyone on it, Contests it. We really dont have to complicate the idea so hard.
