Perks and behavior options (adding more strategic thought to coc)

To add more strategic thought into the game i have proposed a cool idea. what if there were perks and behavior option in troops and defenses? I havent fully thought out any such perks. The perks would be unlocked by experience level, this would motivate players to donate to their clan more often and be more active. The perks would be setup in tiers, the player may toggle one perk on in each tier adding up to maximum of 3 perks. What these perks would accomplish is strategic diversity, not every wizard tower will be similar, not every barbarian will be similar. this will add a lot more thought into the game and would be more fun, choosing perks and imagining how they will turn into effect on the battlefield.

Example perks for wizard towers:

Tier one:

Lightning shield - deflects the first lighting spell dropped on the wizard tower

freeze shield - deflect the first freeze spell dropped on the wizard tower

Spell blocker - hits any spell dropped in the vicinity that isnt lightning or freeze, makes the spell weaker but not fully destroying it.

Tier two:

Lightning - Normal default wizard tower attack

Fire ball - increased radius, slightly lower dps

*couldnt think of any more for wizard tower sorry*


If you like the idea and come up with your own perks, even if its not an entire tier still comment it, ill edit your idea into this post making it easier for supercell developers to see it.
