It has very good foundations but the maps and flow are beyond atrocious, and I believe 80% of the problems stems form that.
Everything is set up so you can get blindsided at every moment. They're a swiss cheese without flow, rythme or reason.
When I get out of cover to shoot at someone, I always assume that spending 2 seconds outside means I'm dead, and I need to kill in less time than that, or just ket killed. It doesn't help that you can get sniped from almost anywhere, and snipers are very easy to play in that episode.
It feels very cramped, I have no breathing room, doing wide flanks isn't possible like in BC2 or BF3.They're basically TDM maps around some objectives.
You can notice that easily in breakthrough : The offense territory is sometime a few meters away from the objectives, there's no neutral zones at all, you get out of spawn and you have to move 2 seconds to be in the line of sight of the whole map.
I feel like their warzone is a massive flop, they're behind the curve, doing an extraction would be a better move.
