Why more players don't buy the Uber pack

Sorry I this idea has already been posted, didn't read every comment but.... I think Avatars are a great idea!
In a game called hero academy, which many here play, there is a shit ton of avatars to choose from. I have literally spent around $8 on avatars for that game. Not because I play it a lot, simply because I want to look cool :3
In outwitters everyone jus has that boring soldier avatar according to your race. Well what if OML charged extra money for a runner avatar? Or heavy? Medic? And so on.
OML can then charge extra money for Special unit avatars. Therefore if you see one with a special unit avatar, you know they bought the most expensive, most bad ass looking one.

Don't know about you guys but I would definately pay extra money just to look cooler in game.
