Manual, doesn't matter if the monster is stunned, asleep, staggered or anything, half the time the clutch claw picks where it wants to go no matter where you target. It's garbage.
Also, if someone wants to say I'm doing something wrong or playing wrong, please explain to me why I clutch to a tail or a head, it goes to the opposite part of the body for no reason, even if the boss is not moving.
It''s definitely not half the time, but it basically uses a hit detection on the projectile so if say a wing gets in a the way it'll grab that, and cause it's fired from the side, it also will catch stuff that's not straight in your visor. That said it still mostly target the right spot, most of the time I wanna say. It's just not pinpoint accuracy.
There's a bunch of stuff that's annoying with the claw, the targetting yeah but a bunch more. The flinch shot wall detection is garbage in several areas, leading to the monster "sliding" against the wall instead of getting hit. The coral guiding lands entrance area is especially bad for that, the waterfall area is basically a big fake wall and you never get a flinch shot if you aim at that.
Another thing is how clunky using the claw on some weapons, IG and Lance specifically not sure about others. The whole "hold the button then press R3, but don't press it too early because it does nothing" is really fucking annoying, especially since you generally want to claw quickly, but if you go too fast and then press circle to launch the claw on Lance you'll instead start a counter claw, which basically wastes a full second before you can try again, so your chance to claw is long gone after that. It wouldn't be so bad if it buffered the R3 input, but it doesn't, you have to wait depending on the animation that was playing when you pressed L2 to finish before you can R3 to get the claw out. It's frustrating as hell and there should be a setting to turn that shit off, just let me claw directly and press R3 to enter the special new block slinger stance instead. Hell just remove the whole thing, I don't need to get another shittier block with L2 to begin with. The idea is to open slinger block stance stuff but they could do that with block > L2 instead.
Then you have the anti out of bounds nonsense. It's especially horrible in the lava area in elder recess, grab anything, monster walks over a lava area, you get dismounted. Use the claw to turn the monster for flinch shot, over the lava, dismount. It procs that crap all the time if you clutch a monster flying too high too, the "ceilling" in the area is so low that getting on top of Kushala when he's flying high above will dismount you. Spend 4-5 tries trying to even land a flinch shot on Kushala with rocksteady because you keep dismounting(and dismounting into tornados too, great stuff).
They should also make wounds last longer when solo. It's annoying having to use the claw so often especially since landing it mid fight is a huge gamble. They have the special exhaust animation thing for clutch claw rebuff, but it's unreliable and it absolutely doesn't help if you're playing a light weapon since you'd need more than one hit anyway. Then again just remove that whole thing, shit's dumb, make everyone wound in one hit and make slinger ammo drop for everyone but randomly(or keep the heavy/light split for that specifically whatever).
