wandering I really recommend you use Enemy Sensor if "gank squads" are a big problem for you. As a Souls player who is used to carefully look around most new areas, and who plays with headphones so I can hear the growls of various enemies before I see them, I have rarely been ambushed, though I did get grabbed by a nure-onna or a perched enki from time to time.
But since I've been spamming the Divination spell all the time (best way to accumulate proficiency naturally without grinding, apparently -_-), and it lasts quite a fair bit, I don't even need the Enemy Sensor modifier on gear as it automatically has that effect, and shows enemies on your mini-map.
Moreover I agree with using ranged and stealth tools.
Ambushes and gank squads aren't really a huge issue IMO. Some nastily placed and barely visible holes are cheaper, to me. The early part of The High-Spirited Demon (5-3) is the worst there.
Actually, I think my biggest complaint about the game has to do with visibility. Dark Realms, ok, I guess that's the point, but outside of that, why is bloom and a smoky/foggy effect constantly active? Makes it really hard to see where you're going sometimes, and it's just generally unpleasant and makes the game look visually worse than it could. Eh.
Yeah, I tend to agree with that.
And the kodama and scampuss!!
