So now Tirion is better tier than Murgur? Absurd. I've never seen him on ranked format neither on YT nor in my games this expansion. Also, I would definitely demote The Storm Bringer in wild and remove Brightwing from wild ranking.
Imo Cairne Bloodhoof is not a staple in any strong decks. I haven't seen it on ranked since release of the Barrens. I think T2 would be better if it's playable in strong decks but there are much more universal cards.
I think that whole Classic + Basic card set is now called Legacy and so it should be named Legacy Set in the ranking and rated in all tiers in wild at least if these cards are not doubled in the Core Set that is available in Standard (then 3 top tiers are enough). Sorry if that all was descripted confusingly.
For me, Zayle, Shadow Cloak and Whizbang the Wonderful have always been too weak for tier 3 but now it is clear that they should be demoted and they are not helpful for new or returning players since Blizzard gives away free decks. Lord Jaraxxus on the other hand was changed to a hero version (the craftable copy is the same as the core set copy) and so it shouldn't be tier 5 in wild or at least the description should be different. If you demote King Krush in standard, Beastmaster Leoroxx should be demoted to tier 4 with him. However, I would leave them in tier 3 for now since they are more universal that Halazzi or Flark which are also tier 3 but in wild. Instructor Fireheart is now very playable in most shaman decks so I think it should be tier 1 now. Dragonqueen Alexstrasza must be played in all highlander decks now so she deserves tier 1 again.
