Gem Boosting Still Needs Improvement
This Halloween update is cool and I love it. Especially the boost pause in maintenance break is sweet. However I think this still needs to be improved.
As we know, we can boost a barrack for 2 hours with 10 gems. This means, people who boost cannot stop playing within this 2 hours because even though the barrack is not training troops the boost duration is still being consumed, and most players don't wanna waste the gems.
What I suggest is that boost should be stopped automatically when barracks, factories, collectors, heroes stop working or healing. When they are stopped, green glowing turns yellow, like the paused boost in this Halloween update. And no resume button is needed because no gems are gonna be wasted.
