I think it'd be great if energy tolls for machines and gates were modified so that knights could satisfy energy requirements by pooling their energy; be it CE or ME. It'd be like in the Blast Network game where you have to bribe King Krogmo, and fill up that progress bar with energy contributions. This would be especially helpful for elevators, since you could bring your friends along more often when they are out of energy. So, one person could pay the whole fee, or multiple knights could balance their energy. This would be extremely valuable since the everyone in the party could make sure they have enough energy for reviving. This way, players who are are skilled but low on energy, would be less of a burden to the entire group, thus contributing to the overall multiplayer experience. There would have to be some limits of coarse, but I don't think that the elevator cost should be raised; thus making independent exploration even more difficult. The possible negative side to this idea is that players would doubtlessly trade items and or crowns to make use of, or extort it. But hey, that might be a cool way to introduce mercenaries to the game.
