For everyone in this thread, if you have disadvantage on a roll that you should *never* fail, then your chance of failure with Larian's implementation goes from 0% to 10%. Instantly. Think about that, your character should never fail at something, and instead they fail one time out of ten attempts. That is huge.
You could always change that. Reroll a nat 1 and only fail if you do it again? lowering the chance of it happening. There would be miriad ways to do this. Personally i would not remove the system. But think about what kind of disadvantage you have. What does it mean? A rogue trying to pick a lock, coughing inside poison gas, may fail more often than one that just has a little dust in his eye. I just think its a bit hard to implement different type of DA.
