Tech isn't what is broken. Nerfing tech doesn't fix what the problems in EVE are. Not to mention the way CCP is going about it with Alchemy removes yet another part of the sandbox you as a player had control over, market fuckery. So instead of people who own a resource being able to dick with the market, CCP has introduced a mechanic to put a soft cap on it's price.
This is taking away from what EVE is. It nerfs EVE, not tech. Tech, after this latest change, will continue to remain the most valuable resource in the game for a few reasons. The main being the manufacturing process which tech is used in. It's entirely unbalanced and full of hard bottlenecks. Other reasons will be when the prices of ships and modules drop and tech being the bottleneck in the manufacturing process, will make sure that any alliance who holds it will have far less effort to gain the income and support their members.
While I believe there should be a supreme valuable item in EVE, I also believe that the players should have a way to determine what that valuable resource is. Not a mechanic CCP introduces to help prevent market fuckery.
