Future Changes regarding Upgrades und TC

[TKF]

Yes, I forgot to mention: healing aura have to affect creeps only, of course.
And amount of healing should be the same as single factory does to player.

LOL that's makes the troops nearly invulnerable (You know when you're attacked by a few creeps while healing, you don't get killed, and when it's hard to kill a tank in healing, then try to kill several creeps with that amount of healing) Perhaps half or third of factory healing to not exaggerate it. Or a pretty decent healing amount that perhaps makes them quite healed when the next enemy wave comes. Also put a visible aura that the players can see who got the healing aura.
