Little to no progression, games are repetitive and formulaic. If you like top or jungle, positions in the game, then you are out of luck. There is a few champs in top that lend it to be a terrible, harsh, and unfun experience were they are better than you passively. If you want to beat them you must be a step above and on equal or losing ground you will just be smashing your face into a wall as your team yells and belittles you. Jungle has problems with experience and you will likely be one to two levels behind and if you start losing you might as well stay at base as then you will at least not be giving gold to your opponents.
