So unbalanced

The game has characters Which can be upgraded for example "Witch" she is fine at level one but when you upgrade her to level 2 it cost 430 coins or at least something In the 400s and it barely does any thing even though the stats say it boost up your skeletons. But what I really hate is prince he is way too over powered to be an epic it is so frustrating and when he takes down a tower with just 2 hits from a charge and 3/4 for your characters it is so annoying and I know no one is going to read this because its way to long.
