The Pink gas shouldn't damage you immediately when it spawns.

If it spawns it's already dangerous - you have to drop what you do and either get back to the elevator with everyone, or at least find a safe room to sit out the anomaly.

Right now as soon as it spawns (indicated by a rumbling) you're almost guaranteed to take at least 10 - 20 damage from the ticks before everyone is in the elevator. This is not good, because this means you can lose a run entirely based on bad luck with absolutely no counter play.

I tend to agree, especially since you may not even notice it's coming until you have 5 seconds left to run.
