I have a suggestion.
I noticed in the shop you can use gems to refill world and raid energy but not titan. There are times when the titan is a 5 star or near the end of the attack clock that being able to refill could help my alliance beat the titan
I second that! It might even get me to start purchasing the gems to get the refills.
We had 17k health left on a 5 star titan and if we were able to purchase a titan energy refill that would have helped!
With the limit at 12* for now it would make it where the whales would never loose a titan.(they probably do NOT anyway)
