Filibuster Deal Puts Democrats In a Bind

Can someone tell me again why stupid conservatives were upset with this "deal"? What is it exactly that they gave up again? Seriously, I can't think of anything. I know they didn't get to go all nuclear on the Democrats, but the result was still the same, they got everything they wanted. It's like a mugger getting upset if his victim suddenly opens his wallet and gives him all his money as a gift, before he actually gets the chance to mug him.
