For the record, I liked Rock's moveset in SC4 a lot more than his SC3 moveset. Of course it's still nothing compared to the SC1 days, but they gave him a lot of two-way options and interesting command throws.
You are right, he gained some options in SCIV he didn´t have in SCIII. But those are almost all the time just "throw-setups" or throw-combos. Stuff that is
never guaranteed.
In SCIII, he could deal very good and guaranteed damage with moves like 66BCH 22/88AA, 6KCH 2A+K and his B+G command throw was much better than the SCIV version.
And he still had old 1B, a better 1K(ring out on NH, better 2A+K(ring out on NH, his FC3K bullrush RO´d, good UB(3B), he had 3KA, could RO with both A+G and B+G cm-throw!, his 4B was
mid! and he had his awesome spiral axe version from SC(DC).
I think SCIII Rock was heavily! underrated. ;) Players like Keev and myself proved that in our respective country.
But in the end, it should be correct that SC(DC) Rock was the best... If Bangoo is in SCV then i demand! the old axe Rock "abandoned" for
whatever!? reason as Bangoo´s weapon. That would be so cool...
