Like the game, but disappointed

I like this game very much aside from the community, but when you work also season to get to promos just to be crushed 1v5 by a Nasus it gets really discouraging. I wish riot would do more to balance champions so each champions strength and weaknesses were balanced. This is a team game where the 4 or 5 should contribute to team victory, not just one. I don't have time right now so ill write more later.
