I've been re-reading the rules for Age of Sigmar, and there are a couple of points that I'd like to clarify.
1. Are the free PDFs still valid? I see that warscrolls are sold at £10 each on GW's site, but it doesn't say that they replace the free PDF versions, only that they include more than just rules. I assume that the PDFs are still, therefore, up-to-date. Is this right?
2. Similarly, is the free four page set of rules still valid for basic games?
3. I note that circular bases are now being used for the majority of infantry and cavalry models. I cannot see any rules explaining what type of bases must be used in the PDF though, so is this an aesthetic change only or is there a rule which stipulates circular bases must be used?
