I'm not sure FS3 gets singled out here since no game system (that I know of) is performing 1000 rolls and averaging them to determine success/failure. Maybe in WoD you can min-max a whole lot more to have ginormous pools, but presumably those chars should be fighting equivalent challenges. Maybe the one thing in FS3 is that there's less differentiation in what you can do or what you can fight, but that goes with the setting, too. Only so many ways a Viper can pew-pew.
It does oddly get singled out more often, a new game comes on, people ask what system, the new game host says FS3. Then it starts again, people will avoid it because of FS3. The first post is negative usually because FS3 is being used it seems.
The stats are always as @faraday has said, more chance of success then other similar games (WoD/Fate/etc). No one attacks new games using those systems because thise games use those systems. But FS3 gets unfair guff. I think it's because it has popularity and a few places use it both because they recognize the basics (dice pool of attribute+skill vs # .. Each die over is one success) from systems like WoD and it's easy to install and get running.
I agree dice on the average game using FS3 aren't used enough.
Also the any target under a certain number is auto success. This has always applied on FS3, the shooting range is a given, normal mundane tasks aren't rolled, they're auto success, dice are fur high intensity situations when I've seen them used.
