If you want to achieve anything in this game, expect to put in years of effort to get a half decent lineup, and by the time you get that, the characters have been superceded with better ones. Alternatively, spend £100 per character to try and keep up. They are releasing new content, which is good, but as it takes a lot of time or money just to get them, the game just falls into a monotonous grind with no actual enjoyment in the game.
