I agree with many others here that PPVP Kate would probably be a greater concern than Faust Whiz. A lot of the MWL targets NBN FA, so making that corp stronger would make access to clot more important. PPVP Kate was a beast at least on par with Faust Whizzard, it would be interesting to see a meta with both of them, as they are both strong against their opposite's weakness (Kate strong vs FA, Whizz strong against glacier).
Interestingly, I think that an early Scarcity of Resources is a pretty cool counter to whizzard's early game, since he needs Wyldside as early as possible (and to a lesser degree pancakes), and uses a decent bit of resource economy. 2c may not seem to be a big deal, but for a runner setting up and depending on so many resources, it is a pretty tough opening to work out from.
