Rogue - Assassin Changes

[Chai]

Agree, but it shouldn't be to nerf to Coup de Grace (except maybe the interaction with Improved Precise shot...). Assassins should just get something better. Bottom line is, single-target insta-kill isn't really that powerful, even when it almost never fails.

What I suggest:
Assassinate can work without sneak attack, and works as current in this case.
With sneak attack, Assassinate grants no save (i.e., auto-success, barring immunities), and has its cooldown reduced based on what the DC would be (something like, every 25DC beyond 10DC halves cooldown)

If you guys think 5 levels of bard is powerful, this would usher in the new era of 15 paladin 5 rogue.

With all the easily farmed FOM items nowdays, sleet storm scrolls would turn anyone with 5 rogue levels into godmode.
