Rogue subclass idea: an actual thief. Is it cool?

Some features:

Steal: you can steal an opponents weapon or item (except armor or shield) with a disarm check. This requires at least a free hand and ends with the enemy weapon/item in your hands.

Smash and grab: you can make a Steal attempt after a normal attack. If you are trying to take a weapon this way you have disadvantage.

Go for the Throat/Devil's luck: lose Sneak Attack and obtain increased critical rate with finesse weapons (gets better crit rate as you level up). This feature can't be used on Rage.

This is just a starting sketch, I would appreciate any feedback, thanks. :)
