i thing the troops which is level up to max level should be transform in to some thing much more power full (not too powerful) for example :
barbarian level max can be update into super barbarian ( he has two sword ,and a better armor )
archer level max can be update into super archer ( her archery turn into a bow that she can shoot faster )
goblin level max can be update into super goblin ( I don't have any good idea, may be he can does splash damage with a magnet)
Giant level max can be update into super giant ( I don't have any good idea, may be can take more damage from defenses)
wall breaker level max can be update into super wall breaker ( after he explode himseft his boom will fly out and explode one more time with 1/5 first damage )
balloon level max can be update into super balloon ( he can shoot boom like wizard but the damage will weaker than he through it , it faster and can dodge air defenses )
Wizard level max can be update into super wizard ( Call the lightning like lightning spell but only one strike )
Healer level max can be update into super healer ( Heal in a larger area every 2s like heal spell, but she can move with the troop )
Dragon level max can be update into super dragon ( I don't have any good idea, may be two head and can hit two building at once ?)
P.E.K.K.A level max can be update into super P.E.K.K.A (He will has two fire sword )
To not make the game too easy, the price of update won't cheap, and make some item like:
Super sword for barbarian super update
The Bow for archer super update
The Magnet for goblin super update
The amor for Giant super update
Boom for Wall breaker super update
Grenade gun for Balloon super update
A Lightning ruby for Wizard
A Heal Drink for Healer super update
A Magic fire for Dragon super update
A legendary sword for P.E.K.K.A super update
To the troops not too overpower, we can reduce the damage each troop that make they strong enough to fight
You guy can give me more idea for dark barrack
I hope the next summer update will use my idea
