Stick to Topsy's process, because it's well thought out, thorough, and measured. The approach will reflect in the final product.
The primary reason is because each person involved in this process is fixated on only a topic or two because of the assignments they've received in the suggestion phase. Yanking everyone out of their individual topics of comfort will give each contributor a better understanding of competing modes of thought and therefor a more longitudinal view of the game. TLDR: They'll make better decisions....
Also, putting all minds to a single topic at a time brings greatest focus, broadest consideration and optimizes pace.
Let's proceed with no further hesitance, please.
EDIT:
Maybe I've just cooked this up in my mind, but I assumed that polled players would be making the largest decisions when it comes to selecting fixes and solutions.
Example: We'd run a poll that would say "Hey our last poll indicates that the majority of players want something to adjust shooting. We've put our minds to it and come up with 1: Major change 2. Moderate change 3. Minor tweak Please let us know which you prefer."
Then we'd be charged with putting their wishes into effect.
And I'm imagining frequent polls. Sound alien? Am I the only one thinking this? (It's ok if that's the case. I cogitate more than most, so the condition stands to reason....)
