NEW HEROES! 'Make Your Own Hero'

What if you could take any troop and feed it Dark Elixer yourself?

The idea is, you have an empty heroes pad that any elixer troop can be placed on. Only one troop at a time and there will be only one pad. Whilst the troop is on there you can feed it Dark Elixer so it grows into a new hero, the troop can be changed once the current troop becomes a hero.

So this would basically be a 'make your own hero'

eventually you could get every elixer troop turned into a hero and levelled up to lvl40 (as I've already said, only one troop can be used at a time).

if you decide to change which hero you have, the previous hero will still keep it's level and individual ability (if you've unlocked it at lvl5 of course).

I hope this made sense, just a quick idea :)
