Thanks all. I’m going to dump that ring in storage. I agree some weird stuff going on, especially finding that higher level blade in a WoD drop. When I say higher level, I mean as I’m just 57 (before I quit last time I started a bit of Legion, then started back deciding to do a “completionist” type of thing on all the old content, so never really moved into Legion).
So when I came back a month ago, they had reset me at Level 50 with a new set of relevant gear for that. And the WoD blade that dropped is actually an improvement over the blade I had on that reset. Getting a blade from WoD that outspecced the 247 gear they gave me is just…odd.
Also, I did try the “Chromie time” as I’m runnng the old content cleaning things up, but since my intent on the old content is just to gather mogs and achievements, I didn’t see much point in making things harder / replaying the content on lower level. I’m just running dungeons and raids smashing everything as fast as possible.
I did “freeze” my character at level 57 as I don’t want to keep leveling, becuase then when I start in on the Legion content I want to level up correctly there, no go in there smashing everything right off the bat also.
I may use Chromie time on some new alts, have a lvl 17 mage, but to be honest I’m taking that character through in chronological order or content anyway, so no need.
If I create a new alt and decide to use that alt starting on current content, I may use chromie time. But I’m just going to take that mage and make him progress in order of the expac releases, so I can relive all that content again in order (I started on original WoW release, and actually bought everything on CD. For Legion, I think I donwloaded that, but did buy a “Legion Collectors Edition” that is still setting on my shelf in the plastic wrap. Those are worth about $300 now. 
As a side note on that, I wish when I was a kid I had the foresight to buy a bunch of things, especially toys and gaming things, and keep them in original packaging and stored them. Can be a lot of money made for that stuff I threw away.
Thanks again!
