4 star to one star. When u are reaching end game. It will be a p2w heavily (consider top 1 p2w spend needed). they start not giving reasonable reward and start limited beneficial event under year 2021 force us pay usd 100 for nothing. Server merge cause hard get reward. More stress on pvp. Gap power from p2w is still huge. Item to raise cp is getting more lower rate which frustrated u can spend 100 usd for 0.1% power increase. I lost 100 combat power after month of grind. Truly not worth to play
