Pahimar, the maintainer of EE2 and creator of EE3 knows how unblanced EE2 is. That is why hes changing the EMC system greatly for EE3 (And my source for this is him directly, from his livestream the other night). He said (may not be 100% correct) that he is having the recipe items and such have a dynamic EMC value based on what is contained within the recipe. So while, say, a sticky piston crafted with a slimeball may be worth x EMC, a sticky piston crafted with sticky resin will be worth y EMC (just an example).
Thats about as much as I remember/know. Go check out his twitch livestreams if you want to hear more directly from him.
ALSO: If you watch any of his streams live, DO NOT mention Technic or Tekkit. Remember where you are.
