Hero upgrades need addressing

Hero upgrades are a pretty big complaint amongst most players. Hitting the upgrade button almost any other time in the game results in an expensive, time consuming, but ultimately worthwhile change to whatever is being upgraded. Troops and defensive structures typically get a nice buff in dps and hp, whereas storage and mines/pumps get a nice buff in capacity and production. Hitting the upgrade button on a hero causes a lot of consternation and reticence. It is expensive and time consuming; however, it lacks the worthwhile results that one typically gains from any other push of the upgrade button. The hero gets enough dps upgrade to possibly take out a butterfly and enough hp upgrade to take one more level 3 cannon shot. On top of that, they are unusable both in total village, and in clan war attacking. It's bunk and needs to be more worthwhile.

Totally agree 7 days without a hero in war or raids is a big pain but you actually need 5*7 so 35 days to get the next ability level which is the only noticeable benefit. Got to change something.
