Not sure if this has been brought up, after searching I gave up looking.
Anyhow our alliance has been stuck on 7* titans for some time now, due to lack of consistency. Some ppl only attack enough to keep them in the alliance. I feel like if the leaders/co leaders can reward the ppl up top then it would give those non consistent members a strive to become better and attack more often. They may even try to level their heroes faster. I’m sure our alliance isn’t the only one with this issue and I believe it would solve it. So maybe make it so alliance leaders can gift gems, items, or heroes. Or give alliance leaders so many gems a day in a separate chest that can only be used to give away. Just kicking the tires.
