Co-op desperately needs new maps. I really don't understand why we can't play arena on some of the DLC maps.
it's clear Co-op was an after thought in everything.
the Siege mode on maps such as 'Lost City, Sanctuary & especially Oasis' is a disaster which goes to show why all 3 modes should have never been combined then Co-op would have worked on every map.
It's relatively safe to do Gold Rush on Highrise though. Desert Village can be a nightmare in Gold Rush. Oasis isn't much better with the enemies spawning right next to the idol. Village is the worst from an AI perspective since they all gather around the wrong chest.
Gold rush is pretty easy in Desert Village most make the mistake by going the obvious route I tend to go up the stairs that takes you the highest area on the map which then takes you directly to the chest.
Oasis is the worst co-op map by far. The Brute will spawn right in the two of the siege zones on later rounds. I've had him drop down right next to me several times.
Highrise is pretty annoying too with gold rush.
I think High Rise is one of the easiest & best maps for Gold Rush & Co-op in general.
Highrise is definitely one of the best co-op maps but because of it's bad reputation in competitive it isn't chosen a lot. I've never had a problem in Oasis; I usually have good luck and the brute spawns on the other side of the map.
The map which I find infuriating though is Syria. The siege areas aren't even siege areas... I mean you have no space and just about no cover. If an enemy tosses a grenade in one of the siege areas it can wipe out your entire team.
Besides, its bad rep comes from people who don't look where they jump.
Or, you know, people who assume everything is climbable.
