Hero recharge for 2x attacks
It's stupid I can log on to two full armies but can use my heroes for only one unless they take almost no damage. The game, especially at th11 and up, and even more so at higher leagues, is balanced around needing heroes to attack. We should have one recharge time that allows two uses then a recharge based on damage taken (or something that has the same effect).
This is also essential to legends league. It's crazy annoying to try to log on EIGHT times, each spread out by 30 minutes or so, EVERY DAY. Trying to do that makes me dislike the game: it's an annoyance that makes me want to stop playing. SC did a great job making legend league interesting again, but it needs this feature. I'm not going to log in and boost or potion every day. That's a ridiculous solution.
