Troop upgrades and ascend

How about being able to level up and ascend troops . It shouldnt be too hard to integrate if your database is setup the way i think it is.

You kan level up troops. Which is in essense the same as ascension.

Upgrading your troops would be amazing! Or combining them like you do your heroes so they become more powerful. Even a sell feature would be better than just letting them sit.
