Well, I would suggest not to waste your time here. The free to play experience is fine for like a few days. But its pretty obvious you are left only one of either two options: a.) You keep grinding yourself up, waste time on adverts and spend hours in a somewhat pointless game (more on that later) or b.) You spend real money on it "to cheat" your way up faster. And its very pricy, they charge silly amounts for stupid stuff. And its rng. Tactics are useless.
