Everything has a fairly small implementation time. It's the question of do we wanna work on skirmish or co-op for the decision makers.
Also, the current harpoon doesn't pull in, all it does is attach to the ship hit by it and make the physics into a problem with two masses connected by a string - similar to the co-op balloon you can connect to your ship. And the change to the harpoon wasn't a feature but a bug, which I assume was caused due to the development of exactly that balloon in co-op because of the similarities of both mechanics and the timeline of the changes.
That's the age old question. Granted, a harpoon fix isn't a huge priority but overall skirmish needs attention, there are a lot of things un-balanced or broken. We've all seen where co-op is at, I'm sure it's safe to assume it's still a long ways from release. It's already been 2.5 years since they started working on it, and look how far they still have to go with it. So how long will Muse continue to ignore skirmish? They need to learn how to be able to balance time for both.
