Today I found out that Prometheus Lens actually does not burn enemies

I heard rumors about it triggering "Playing with Fire" and I kinda used it for this purpose, but today I actually tested it and it's a big no. Technically it never said it could burn enemies, it just generates a heat field. I guess that made some people think it would burn enemies.

​

So, it not being able to trigger the vital part of my build plus it using special ammo and not having any associated scavenger perk means it's completely useless for me and to most other players as well. I don't see a reason why you should pick this over any other weapon anyway.
