Great video as well as great points!
There is a need for progress. Even though there are pieces of HF17 that have people are disagreeing on, it really boils down to seeing how things go and tweaking from there. If not now, than it will simply happen later. Nothing comes out perfect the first time through and things that just flat don't work can be withdrawn.
Pretty much everything that's done here is a test into uncharted territory.
I feel a series of micro-tweaks coming on now!
