Compound 42: Add a sprinkler system to certain rooms?

The consensus seems to be that the poison-fire combination makes the Tier 3 mission too hard. I tried it twice and had to use 1000 CE revives both times, whereas I don't recall ever hitting that level while testing Legion of Almire.
Perhaps the designers could add a sprinkler system to some rooms? One of the Rescue Camp missions has a sprinkler system, so this could work in a similar way. It could be activated by a switch and temporarily extinguish the oil fires in the room. The sprinkler would stay active for a few seconds before the switch toggled off again.
EDIT: I just completed Tier 2, and it was much easier. I had to use only one CE revive for the whole mission.

I am also in agreement with this. Although I only had the heart to try Tier 2.

This sounds like a fair nerf to the content instead of destroying it with the nerf hammer as some people are suggesting.

especially because the sprinkler would get rid of fired oil but not regular poison oil that isn't on fire, making Dragon Scale remain much better than wolver for this content.
