I don't really mean to justify that map, just wanted to point that out.
To be more specific, I don't remember a single approved map as small as stride-sniper other than Eric gurt railwards perhaps. And we can already see the gameplay the small map casues. Since it's small and 8 players max, it's bound to be dense, there's almost always a player at your screen on max players.
In terms of gameplay pacing, this is as fast as an approved map can get.
