If it wasn't P2W it would be 3 stars as it would not be that bad. But listen... it's moba with hard to grind items that make you more powerful. You have to play forever to lvl up items with bonus stats or just pay to have them. Advantages you can get are game breaking.
You might not understand how 15% bonus to running speed can make you dominant player, but it will not change a fact it will just make you win.
You can farm it yourself for 40 hours vs P2W players... it's just mobile game standard practice or even worse.
HOW?!
