I've been playing for 3 months now and finished almost all of the end game content as a free to play and still using the starter team.
The story is well written. Always on the lore.
Combat is great. Not a smooth animation but it gives adrenaline.
Ranking system is sometimes balanced. Hell, you can even outranked a whaler.
Stamina system is okay. Not a big deal for me.
Leveling up is easy. Not the grind tho but that's normal to games.
The game is VERY generous with their rewards. I play mihoyo games so PGR's generosity is surprising.
I've seen a lot of 1 star reviews acting mad how bad the game is. But I just see some impatient babies crying lol.
