i guess it depends on the game but what games are u comparing it to? If we looking at other TCG games, I don't see yugioh duel links, MTG, hearthstone. Even web3 TCG like gods unchained or cross the ages doesn't have an energy system. I mean people there can only play 10 games to earn their token but after that they can play as much as they want.
I agree that there is no perfect solution but I just don't think this proposal is the way to go about it. i think tournaments was a good way for the people that i enjoyed playing the game to not have to worry about not being able to play cause of no energy.
oh well i could be wrong. we will just see how the vote goes if people really think this is a good idea
