Takes pretty much at least a month to upgrade/acquire most characters. Takes forever to gain stamina( 1 every 5 minutes) and with the base stages needing at least 6 stamina and base elite stages needing twice that its easy to see where this is going. Pretty much the only way to really get anywhere in this game is through spending money. With many people dropping 100s all the time, most general people pretty much get nowhere. There is also quite a few other wrong things with this game but you would need a general knowledge of the game to understand.
