Personal opinion, yes. Its due to map design.
Theres almost no difference between spawnkilling and what happened in the first clip (apartments) because of how small the chokepoint is and the actual ability to move from the spawn to anywhere else. Basically 0 chance to move from the spawn point to anywhere.
The other clips are fine because you actually have options to do something.
And yet, I just listed a number of options you have with the first clip of Apartments.
I didn't see anybody spawning into thin air and getting shot.
Another of the many options is for a SL ot TL to lob a smoke grenade right at the window and block his entire view. This would either force him to relocate (as he should know they know where he is and are coming) or he'll start shooting aimlessly, but in both situations, he'll be dead soon.
You spawn on the other side of the wall and down in the river, there is no vantage point where he was to be able to shoot straight at people who are spawning.
And as mentioned before, they all could have spawned over to cap B and flanked him in 5 seconds and stop his antics.
The fault here lies directly on the Russian team not being able to think outside of the box and just constantly running out with no brains.
That entire building is often infested with Germans even after Cap A & B are captured and they are infested for the sole purpose of slowing down the Russians advances. Without doing so, the Germans are easily pushed back from the Square and Propaganda House.
At the same time, the Russians can close off the chockpoints of where the Germans spawn and gun them down the moment they round the corners from their spawns and towards Prop House or the Square.
And often times as a Russian, I'll take up the house on the German's side at Square (above where they all like to camp out and shoot at the Russians) and I will easily grenade, pick off and chew up anybody below me, in the square or anybody entering the top floor.
Is that spawn camping/killing? I'm not in the objective and I'm on the German's side of the objective, so you'd think that would be worse than what was shown in the video.
