Please let a Exotic engram keep their light level when you focus them at Rahool, instead pulling it back too 200. I have a Exotic engram of 407 power in my inventory, but not willing to use it for focussing, as i have to spend another 8000+ unstable cores to get it back to level the engram is in the first place. As of now the econemie on Unstable Cores is not quit balanced and i wonder how much it wil cost if you go up too 500+ in a few weeks. This makes focussing at higher levels not worth it anymore.
