Thanks for making the thread, hopefully the issue can be sorted out. Prepare for a long post. I'm going to kind of jump from different subjects regarding my thoughts on spawns.
It'll be a little bit before I can get a detailed video up that shows the area of the map during that video I sent you. For what it was worth however, it was during a TDM match. There for, theoretically, spawns should've been available over the entire map, and not limited to objective control. This brings me to my first thought, which is what I'll just call "Spawn Priority":
Buddy System and Objective Control
Without knowing the ins and outs of the spawn system, I assume it operates on a priority system. Spawns near Teammates or Team-Controlled Objectives would obviously be the "Favored" spawns, and would be the ones given priority. I don't know which of the 2 get more over the other (Are you more likely to spawn on a teammate, or near an objective your team controls?), bu I do think that that much is part of the problem.
One thing I've noticed is that spawning creates a Chain-effect on your teammates. When you respawn, a teammate tends to respawn near you. And because there is 2 of you, another respawns, and so on and so on. The same also happens for enemies. Because of this, it creates a situation where the 2 teams, despite massive map size, spawn in relatively close proximity to one another. This is the crux of the problem IMO.
One way this can be solved, is have spawn points get an ever increasing value through-out the match. In this way, un-used spawn points become the priority spawns since their values end up really high. So instead of 2 teams constantly spawning next to each other on a map such as Array, the spawn points away from the action will get higher values through-out added to them since they aren't being used. This should lead them to gaining priority and splitting the action up a little bit.
In objective based game modes, give more priority to objective-based spawns which aren't being captured by an enemy. Not only will this make area control more important in domination, but it should help limit some of the issues of teammates spawning on each other right next to the enemies.
Line of Sight/Focused Line of Sight
Another thing that I thing should be checked out, is "line of sight" spawning. When you are spawning on a point, check to determine if it is within an enemies visible line of sight. If it is, in my opinion, its value should significantly drop. That's almost a death sentence itself (see my video for reference). Because lines of sight are constantly changing however, this won't be the best solution. Values would constantly be changing. So maybe instead of changing the spawn value as soon as someone looks in that direction, you can instead change the value if someone "Focuses" on that line of sight for a period of say, 3-5 seconds.
Spawn Control
To give players a little more control over the spawn system, I think "Force Spawn" should be an option, and not required on playlists. Allow us to choose WHEN to respawn. Not WHERE, but when (within reason, not waiting 5 minutes). For instance, if we could wait an extra 3-4 seconds before respawning, any number of potential spawn points could open up. This idea sounds good in theory, but in practicality, I really have no idea how it would work.
Tac Insert is another thing that needs some changing. The glow is just too big. You can see it from a mile away, and if its close to a wall, even through it. Its also breakable by Flash and Stun Grenades. Make them resistant to those, and dial down the flashing a little bit. They'll be more practical and useable like that.
Anyway, without having an actual video to demonstrate my principles or to showcase my spawns (and the area around), going through text makes it hard to convey my thoughts and ideas. Maybe all of these things are taken into account already, and I'm simply telling you what you know, I'm not sure.

Here is a video giving an overview of the map during the time I spawned. This video shows what was happening at the exact moment I spawned. Keep in mind, this is only 30 seconds long. Theater doesn't allow for much, so its hard to get everything in. A few details:
Team Deathmatch
Only Killstreak was an enemy RC-XD
Map was "WMD"
