Yeah don't get me wrong, Marooner's Bay is still... pretty fucked. D: But as someone with the goal to kill bosses a lot, I tend to be able to handle MB high tide pretty well. Better than normal tide, even. Sure, can just get a bit fucked with bad Boss Spawns (hello 2 Flyfish that spawned in the far back in the mids of CHAOS).
But Spawning Grounds consistently goes the worst. It is just sooo bad with those grates and the apparently mandatory constant Flyfish spawn in THE location (you know which one I'm talking about) -w-
I really do think they need to nerf Flyfish, with all this extra chaos, it is rare for you to get a good chance to kill them.
