Zhorkil is entirely right to lock the thread in general - as it was sourced from an in game event (someone dying) and was populated with very biased views from people from both sides.
However I Still feel this area deserves consideration.
As someone who has played 3 Ninjas at 50 - one of them falcon eye, i don't actually think study, or meditating upon study requires a change. I expect to be challenged on that.
The one thing I have disliked about this skill over the last 9 (or is it 10 now?) yeasrs I have been involved with this game is the fact that is has no counter - unless you are playing a class that can detect hidden.
The traditional counter was always to poison yourself, so you couldn't be strangled - however that has not been an effective counter for years - since people figured out how important Hit roll is in, and how easy it is to assassinate someone who is poisoned if you have high hit roll.
I would propose one - and only one change to this skill, that it be impossible to assassinate someone who is awake (with some special dispensation included for certain qclasses that can't be strangled.) This means that a ninja has to actually suprise someone, rather than just gather study and then sit in a room spammming the skill until that person walks in.
