I'm a huge Dragon quest fan. I've played this since day 1 and I finally decided to quit a few weeks ago. In order to progress deep into the events and story it is p2w. Even then the RNG to get S tier is 1-5% on the special summons. I've only ever spent $20 and grinded gems to get some decent S tier champions but the game became so much of a chore and battery drainer I've decided to stop. If you're a casual player and don't care about getting the top prizes then feel free to try it out.
