I really wish they had kept d10's... considering I have a few nice sets of 10 sided dice (for reasons lol) At least dice can be cheap.
I'm very wary of blank sided dice, and while only 1 side is truly blank only about half of the sides actually contribute to success. I can easily see rolling 8-10 dice and failing to gain more than 1-2 success... People have said that "If you are rolling a d20, and you must roll over at least a 15 to succeed, then you have 14 blank sides." I must retort that when rolling multiple dice you can combine 2 that are less than 5, and have a 5 or more between them. Add to that the luck of an 8 or 9 and you can pass a roll without such risk of complete failure. I cannot get anything from 2 blank side dice and while the dice do explode, there is still only a 50/50 chance I'll get a success from it.
Putting ease to my mind is the fact that the system (as far as I've read it) sounds almost completely narrative. You shouldn't be rolling for things you are expected to do, so they shouldn't randomly completely fail at a trivial task even though the dice might allow it. I do wonder at the player satisfaction of going through a scene and maybe rolling the dice 1-2 times to complete everything - compared to previous systems with more mechanical engagements resulting in several satisfying dice rolls to both complete tasks that have now become easy (and even venturing raises to maximize on the now-effortless activity) as well as rolling the numerical reward (damage, influence, ect) for their success in addition to the challenging rolls they can sweat over, and spend their void on.
I do not believe I could trust these dice to reliably let me wipe my *** if I had to roll for it. I would invariably fail, resulting in a moistened bit breaking through the toilette dabbing my finger in filth causing me to frustratingly smear it across my bosses desk as I return to work possibly getting me reassigned to a distant office where I'll have to deal with questionable locals.
I'll give it a chance, but I hope to see some element of reliably adding at least 1-2 successes automatically to some rolls to offset the coin-flipping type dice.
