It could well just be my mouse. It felt like the character orientated immediately, which allowed for fast paced movement, I wouldn't remove that.
But I did mess up my jumps a few times due to my mouse having moved a bit during the jump (I think). Could well be I need to practice a bit more.
I don't think either are wrong. Adjustment time would allow for more scripted jump sequences, instant move allows for a higher skill ceiling.
