Wow man. I had some trouble in beta but nothing like what you're experiencing.
I don't think the game cheats. I've made plenty of saves against poison, knockdown, stun, etc. And I've had plenty of luck in knocking down enemy mages, soldiers, etc.
What is your party made up of? That could be part of the issue you're having. Some parties are going to have a more difficult time than others. Maybe you need to adjust yours to fit your playstyle.
Also, if you're clicking on the ground by mistake and moving I think you're playing to quickly. The cursor has a noticeable change when you are going to execute any kind of attack. A little patience is probably called for here.
