Er, if by finetuned you mean nerfing it by 2/3, I guess...
My BS is now consuming 3 deut per second instead of 1.. Which means of the 730 fuel I can carry, I waste 180 of it just charging the thing and then only have 3 minutes of cloak instead of the 11 I had before. 3 minutes of cloak isn't enough to do anything, really..
