Ability to donate spells

Have a separate counter where u can donate spells to CC to use either offensively or defensively. Defensively they would have to work slightly different. My idea for defensively:
Lightning spell: cause walls to be electrified causing damage to any unit attacking walls. Damage depends on level of spell.
Healing spell: cause building hit point regeneration. Hit point total depending on spell level
Rage spell: to work somewhat like a "confusion" type spell where attacking units attack each other for a few second time depending on spell level. Units would have to enter CC radius to activate.
Jump spell: cause walls to be twice as high not allowing flying units or hogriders to go over them.

The need for a second spell factory would be necessary as well as an option to use troops and spells offensively or defensively and having the player choose to activate them defensively or not.

Does anyone else think this would make the game even more awesome!?!?!

Wish u had access to another spell factory so u could still have spells during the days when upgrading.

Or should be able to receive/donate spells

Or simply continue to create spells while upgrading

Sounds good, except for the jump spell....what is the point of flying troops when they can't even go over walls? Hog riders is understandable, but dragons and minions should definitely be allowed to pass through walls...no point using them otherwise if they can't even fly over walls.
