Well, up to Tier VII you might enjoy the game even when your team are potatoes. But not after that point, and it becomes outrageous at Tier X as every last potato will make it there eventually and won’t level up nor quit, so the amount of bad players at Tier X is unbelievable.
Also as a F2P game, it’s designed so you must pay in the end.
Don’t get me wrong, I’ve been playing it on and off for 3 years since release, but it must grow with you becuse frustration at higher tiers is a thing and taking breaks is necessary. Right now I still sail my Tier Xs but also are grinding up tiers VI and VII to enjoy more the game.
