If you want to limit the power of Slice and Dice, maybe have it lose a die in damage? For example, spend 3d6 to deal 2d6 as the pseudo-extra attack. That's going to be weaker than most extra attacks anyone gets. Otherwise, increasing the cost to 3d6 (ie. sneak attack damage at 5th level) was probably a good idea. I fully admit I didn't consider when you'd be able to use it when I first suggested a cost of 2d6.
If you're really worried about it, you can have Improved Dirty Trick unlock the alternative options.
Please do take your time, and I look forward to seeing what gets added.
