Thanks for the responses both:
Melllllkor and
Mellkor; I made a typographical error of [10] with the 12 second Assassin cooldown good catch. :-)
It's quite possible to double assassinate in "ideal" scenarios. It's mostly irrelevant; I was actually basically agreeing you, in that the player isn't likely going to get dozens of kills in that timeframe. I certainly never mentioned how many specific kills within 1 minute.
Correct, in that if you are getting "hit", and damaged it's going to take you out of stealth...
Note: nowhere did I mention; I was getting "hit"... I clearly stated the monster was already: "aggravated and swinging weapons at me". Let's re-examine what I said.
Perhaps I wasn't clear enough; I wasn't being "hit", I thought that would be frankly obvious since to Assassinate you still basically need to have entered Sneak mode prior. However, now you don't need to land the Sneak attack prior to [Assassinate] thus can be visible to the annoyed monster that can be attempting to hit you.
To me personally, it's looking like you've been misunderstanding (misreading) somewhat I wrote because you'd be loosely preaching to the choir in certain places. :-)
