Stat values

This is a question for Riot. Having submitted a support request asking the below question, I was directed to ask here (apparently Riot customer service can't/won't ask other departments for info). As I have become so repulsed by the direction and balance this game has taken since I started playing, I'm trying to craft a theoretical overhaul of the game. In order to do this I need to have some manner of ground work, specifically the gold values of every stat in the game. While I've managed to get most of them, I'm still missing a few. I tried establishing a ratio between gold and IP so I could use primary runes to get the data I needed, but there's no consistent ratio. So, I would be very appreciative if you could provide me with the gold values for the following stats:

Energy Regen Energy Percent Bonus Max Health Percent Bonus Experience Percent Decreased Time Dead Crit Damage

Everything else I've been able to lay out so far is derivative of other stats I have values for, so this will get me the foundation I need to move forward. While I don't expect this to actually get a Riot response, I have no other avenue given how I'm trying to form the basis for my overhaul. Just coming up with values would be subjective, and subjectivity is one of the aspects of how this game is balanced that I hate so much.
