Ok. So, qualifying game modes:
A/D, single- or multi-stage, 2, 3, 4, 5, 6, 7cp etc are all legal? (Not that I advise 7cp A/D or anything)
Push, with any amount of CPs, in any hierarchy, are all legal? (again, not suggesting, just proposing)
A+B > C, and ALL variants are all legal? (AGAIN, just proposing)
STEEL-esque goal strings are legal?
Teritorial Control is legal.
Not sure what you mean by "in any hierarchy", but other than that, yes.
I'd much rather get PM's about cp variations than try and list what you can and can't do right up front. Reading a list just grinds all imagination to a halt.
