More Heroes... Too Powerfull... Select 2 Heroes to Use for Defense and Attacks

Hey!

So this idea has probably been brought up before, but I want to see more heroes in later updates!

However, with anymore than two heroes at once, attacks and defenses get too overpowered.

To get rid of that problem, when more heroes become available for purchase, the player should be able to select any two heroes to use fire defenses and battles. The other heroes are held in storage. (But not a new storage, something like the Town Hall)

Question for my own idea: If my idea were used in the game, should players be able to upgrade a hero while it is in storage? Or should one spot be taken by that upgrading hero, limiting the attacks and defenses to one hero being used, or none if two heroes are upgrading?

I look forward to your replies!!

Thanks!

why would defenses and attacks become overpowered its currently 2v2 for heroes and if more are added it would still be say 4v4 the heroes could be bought by both players and used on both atk and defense so using more then 2 shoulnt be a problem

How about this, when you're attacking, you can only use 2 heroes, but as a defense, all heroes can come into play. I think storage for buildings has been ruled out, so They'd have to stay on your base.

that would be cool

Yes, this will make hero ideas not get turned down quickly like mine. Check it out please by the way.
