I'd be ok making skill #3 on that list, but obviously much lower priority. Basically, try to make closer games, but don't over do it.
Vacant and Shipment are out today too. I remember Shipment being a "joke" map so no idea how that's going to play. Definitely a tiny XP farm. I remember not liking Vacant either, but it should be a decent map.
I liked Vacant. Shipment was a lot of fun when they put it in COD WW2. Easy map to get kills and exp.
