When between battles on a streak there is only one button to complete the recruitment before starting the next battle. If I only use some of my troops on the previous battle, I cannot start the next battle until I rehire all of the used troops and wait for that to complete (or gem). There should be a way to start the next battle immediately so that the hire time ticks down while the next battle is in progress.
GEMS, that's the point if you lack patience You're getting rewarded Chest(s)....they're not going to make it that easy
I want this more for sniping collectors than for streaking tbh, you used to be able to deploy a couple gunners, and go straight into the next battle. Now you have to back out, go through an extra two dialog screens, and hit the fight button again from your island.
