I have to say that this land grab mechanic puts me off a little, especially with the pay to win aspect of letting "founders" grab all the best spots first.
Well all of the founder packs give you the 4 day headstart, even the cheapest one. So anyone who gets any founder pack has the same chance to grab spots. And of course anyone who doesn't subscribe, cant get land anyway, so no harm there.
Makes sense to not allow free 2 play accounts have access to building, because if they did, you would just get people making 40 free accounts and taking up huge swathes of land by themselves.
