Troop Saver

I think there should be a troop that saves like 1-3 troops that only take up a certain amount of space and it can increase every time you upgrade it. I thought of this idea when I started to use pekkas and that took so long so I thought how to preserve troops so you don't have to waste your time waiting for it. I think this will help people raid easier like Th 10's because you know when you get a new troop and you want to raid with it then when the raid is over and you want to do another you have to wait longer. This will also save more gems for the gemmers so people with gems can focus more on defenses and upgrading all that stuff. I think this will save more gems for the super expensive stuff like walls which you can use elixer now for but shows and all that stuff. I think this will help people out in the future
