The game is great until a certain point, quite fun and relaxing. Once you reach the current tier of the game though (12 as of writing this), you're forced into terrible mechanics that severely limit your ability to play. These barrier mechanics will force you into very specific hero selections in order to progress, which has destroyed years of hard work for the player base. But up to there it's great! Just stop before the end so all the time and money you put in doesn't become worthless.
