Players may have noticed that there are legendary tokens available, that seemingly create a legendary for a specific class. Those have been datamined on PTR.
Just to clarify how those are going to be used: those are actually--and this may come as a disappointment to some--those are actually what you will earn if you literally have all legendary for your class. Initially, we made it that if you have all legendaries for your spec, you get them for other specs. If you have them for your entire class, then you get tokens to help on alts and get them up to speed a bit faster. It's a little bit of catchup but also makes it feel constructive to keep earning rewards as you play on your main, if you want to do that.
That said, these tokens definitely are something that could see a different purpose further down the line in the expansion. We know there's desire to have a bit more control over legendary acquisition, and the fact they exist gives us a vehicle to do so.
We're not adding lots of legendaries to the drop tables, in fact we're not adding any new legendaries to the drop tables, we're still seeing players on average having a reasonable number, and we've done a lot to balance and shrink power discrepancies between the legendaries out there.
