Info page of troops show the actual level picture of the troop.
I made some examples using photoshop: http://imgur.com/a/Y1u7P when you go to upgrade a building, it shows what the building will look like, i Supercell should do this with troops as it makes sense. for example when a player clicks on the troop info, it shows a picture of the troop level and what it looks like, not just have the picture of a level one barbarian for example, when the barbarian is lvl 5 with the helmet on.
This is an idea i think Supercell should use as it makes sense to do so as the building show this.
