It's just fun all around, and it's only gotten better as I've learned it more. I've been working on S ranking all the missions now that I've unlocked everything and done all three endings and it's been great going and dunking on all the bosses I struggled with in the beginning.
I also spent entirely too long making the decals (unfortunately I stole my copy so I can't upload and share them) for that shitpost build, so I went and killed balteus with it.
The build worked better than I thought it would and I wound up with an S-rank on the run I did for that shot.
Actually, looking at the parts now its biggest problem is just that it's too heavy, mostly from the arms. That core (ephemera) is great for a medium AC, the mind beta legs are better reverse joints than the spring chicken ones but they're still ok, and the head's pretty decent for a medium AC. I went with a full electric status build with the stun bombs and stun needles, so it still does damage. The arms are the tian-qiang ones, and I'd recommend nachtreiher, firmeza, or alba arms instead because they're literally about 10K lighter, meaning you can swap to mind beta legs, bringing the whole build down to around 80K weight which opens up what boosters you can use a bit since a lot of those have ideal weights in the 70-80K region.
That's still about 20K over the light ACs I've been running, though. Some I've even carved away at enough to be able to run nachtreiher legs with them. After spending so long in medium AC builds that go about 290 it's wild running around in something that's going above 350, it dodges so much just by moving.
9/10 game, only real problem is a lot of the weapons are undertuned and a few are maybe a bit overtuned, but like with souls games some things just being worse doesn't matter so much once you've learned the game enough for that not to matter so much, like how I took stun bombs on a pointlessly heavy AC into balteus as a joke without any issues.
The mind beta legs are basically just the spring chicken but 5K lighter (that's 20% lighter) with marginally worse stats to compensate, and thus are great for building what's basically a light AC with medium/heavy AC weapons. Reverse joint legs are great, though, especially paired with the coral generators which you want to redline instead of letting them passively recharge because the reverse joint legs still let you leap when your energy is empty.
As an aside, there's actually a fourth set of reverse joint legs that are incorrectly marked as bipedal: the nachtreiher legs, which are just better kasuar legs but with worse EN use.
