I've been playing around with the dice roller app a fair bit to try and get used to the system before I run my group through it, and discovered that more often than not I've ended up either failing with advantages, or not succeeding with advantages (Is there a difference between the two?) an was thinking I may end up house-ruling it so that you can trade in 2 advantages for a single success.
I'm not too sure how much that will affect the overall game.
