After picking up a Guardian Owl a little while ago, I started looking around for tips on how best to use him. Instead, what I found was a general consensus that he is one of the worst (if not THE worst) heroes in the game due mainly to his very slow mana charging. A bit more digging confirms that, with a few exceptions, the faster-charging heroes tend to find more use than slower-charging ones.
With that in mind, I propose a new type of special ability for maybe a future HotM: Time Inversion. Simply put, the charging speed of everyone in the battle (including the caster, allies, and enemies) would invert for a few turns:
-Very Fast becomes Very Slow (and vice-versa)
-Fast becomes Slow (and vice-versa)
-Average would remain as is
I can think of quite a number of uses for something like that, but I can also see it potentially being far too unbalancing as well. What do you think?
