I am a newcomer to these forums, but have spent a considerable amount of time doing custom Marvel Heroscape stuff for the fun of it on my own before I found out about this forum.
My original goal was to fix the broken mess of random custom Heroscape cards my friends found from the internet to play with. Eventually, I had a pretty good point valuation system on my hands. Applying my system to the original ten Heroes, seven of them come out within a 5 point margin of the official values. The other three have somewhat questionable official values (Iron Man, Spider-Man, and Venom).
I put an awful lot of work into this for just making my own custom builds to play with my friends. After finding out about this community, I decided to polish it up a bit and share it. Please have a look and let me know what you think.
Here is a link to the PDF explaining the system.

Here is a link to a google spreadsheet version of my Excel calculator. You should be able to download it as an Excel file from the File menu.
