Usable heroes while leveling them up
Maybe not for farming purposes, but at least for clan wars. Many attacks in clan war rely heavily on having heroes for your attacks (especially th 9-10) and it would be nice if we could use them. Here are a few of the suggestions:
1. Remove cool down completely for heroes in CW
2. Have them on normal cool down for CW only
3. Make them usable once with a fee of Dark Elixer (500 or so each)
4. Just remove the sleep time while upgrading completely (unreasonable?)
Just a few thoughts. I know having to upgrade heroes is a pain when your clan is in war. The fact that you can use them anytime except when you upgrade seems a bit unfair.
