I did notice something wierd immediately after loading; had an NPC standing near the entrance to the settlement, who was both running in place, and spinning in place, while being half transparent. I went to take a screenshot, the moment I hit the key, he stopped doing this.
Dunno what the heck that was about.
On the note of other changes, Wisps now seem so easy that they may as well not exist. They cant damage you unless you've fallen asleep at the keyboard, since they have no attack and it takes all of a second to kill them. Didnt think they were that hard to start with, since they rarely ever fired the attack they DID have. The only way they might be even a remote issue now is in JtP missions, but even then, in those they'd die even faster.
Come to think of it, the swamp areas are a bit too easy to start with (even before wisp change); the only real threat seems to be the constant presence of the stinging nettles, but even then those do very little damage (sure are annoying though). Which is too bad, they're a pretty neat area, with the way they generate, but they're currently pretty boring. It seems enemies dont spawn there in high numbers ever? Usually I just see one esper floating around by itself every now and then, with random wisps off by themselves somewhere. Currently the easiest area type to run through without having to fight anything, aside from occaisionally stopping to hurl a bolt or two at the wisps.
....as opposed to the Evergreen Forests, which are this screaming nightmare of eagles and crazy fiery things and pain everywhere. That area seems much nastier than even the Deep or the Lava Flats right now. Not entirely a complaint, mind you; they sure are exciting, if nothing else (particularly when the game decides to then put Stinging Nettles on literally every possible part of every surface). I just thought I'd mention it since the difficulty level of these areas seems REALLY far ahead of any other region type.
