Having hit tier 5 on the reputation systems I'd like to suggest larger conversion projects than the 50 marks and 5 processors ones we have now. Perhaps a 1000 mark and 25-50 processor conversion project. They would have the same rate of exchange as the current projects, but would just allow us to convert our resources quicker and easier.
I've got everything i want from the reputation systems already and am sitting on a stockpile of over 12,000 omega marks across 3 characters, i would be converting for close to 2 hours with the current 50 mark projects.
I doubt the project time will be dropped, so why not merge the two ideas to at least enable you to convert all that you want without having to continuously retake the project?
A UI element that you can add how much you want to convert (slider based) and it dynamically calculates how long it will take. If you accept, then it launches that project for that time. One project whose time changes depending on the inputs.
