In 1v1 there are two starting positions obviously... Because of the not-mirrored map design one position is often more exposed to cut off attempts. Thus players agreed on fixed starting positions for allies/axis because in every tournament so far matches were mostly best of 3 and everybody had to play both factions.
People are used to it. I guess players could also make a gentlemens agreement before every match if the rules are still unclear when the tourny starts?!
This makes a lot more sense now. I'll get back to that since my primary focus is to provide a smooth experience for the cup and not leave you guys waiting for hours.
As for the seeding question that has been basically answered by Chexx. Of course we're always open to suggestions but it will at least stay for a month.
Now for the topic that interests me the most. What's the min/max time for a single match in everyone's opinion?
