@Sahto Alot of players don't pay attention to the patch notes half the time (and that's there fault in imo) and only look at the patch previews, so if they didn't update the patch preview page then all those people would be complaining and making tickets on how the information is wrong and they should fix it. Some would say protecting the stupid is a good reason to update it, personally I don't see why people don't just wait on patch notes. As for the brilliant keys, it's a 60 second craft... why not just wait for official patch notes since you save nothing making them in advance...
Not sure if the 1-6 pve path had the cost upgrades reduces since never used that path, but the cost to go from non-raid back into raid path had alot of roses taken out so I assume thats what they are talking about, you are right thought they could of instead of putting 1-6 price changes specified pve-6 into raid-6 specifically is changing.
