Index cards Errata

please GW, please learn from this and just make all the Rules digital with regular Updates, don't stop when Codices start dropping

So as predicted, the cards where outdates the moment they went up for sale?

Well that didn't take long

I wonder if it's any major or just like grammer and typos

Still no fix for the Mob Rule strat for Orks. :/

I'm new to most of this is the errata more of a error fixing update or a balance update?
