Boost time options for army troops
I think it would be nice to be able to choose the amount of time you want to boost your barracks, spell factory, and heroes.
Playing non-stop for 2 hours can be a grind. I think 1 hour would be more manageable, and maybe even as low as 30 minutes.
There are many times I'd like to use my lunch hour to get in some raiding. Even a BARCH army of 120 archers and 80 barbs is going to take me 50 minutes to train. Sure you can mix up the ratio, but you're still looking at having at least 30 min to train up a camp.
Boost those barracks and speed it up by 4x and you can pull off quite a few attacks in an hour, but you are still wasting an hour of boosting and the associated gems.
I'd even support a slight increase in boost cost - 2 hours currently costs 10 gems per barracks, spell factory, or hero. Maybe cut that down to 1 hour at a cost of 6 gems.
Is it too much to ask for an option to boost for a lower amount of time?
