3 stars: I'm frustrated after four years. Game is definitely designed to suck $$$. I've backed down over the last few years and find myself as a leader struggling against those spending $$$ for new heroes that are more powerful than the ones that were great for a few years. Some are spending huge. Try to enjoy, it has kept me entertained for four years but no rewards in return. Just open wallet!
2 stars: Ultimately, this game was a dead end for me, and it shouldn't have been that way. Despite a modest amount of spending, I eventually ran out of heroes that I could level up, and they are everything in this game. New heroes and the items required to level them up are too rare. Effort is rewarded with this dead end; expect to spend.
