For us F2P'ers, I expect to see all 4 SL zones available & all 4 of the leveling dungeons open to us.
While miserable, this would open up brand new BiS possibilities, & new open-world farms; as well as new dungeon gear options. I don't think we'll be able to go to the Maw, Korthia or Zerith Mortis ( They being max level zones ) though i'm hoping that we'll be able to enjoy the rumored refurbished zones on Azeroth.
On the wish-list: It'd be fantastic if some of the presently restricted dungeons were made available ( Auchindoun, Everbloom Wilds, Tol Dagor, Underrot, Utgarde Pinnacle, the Occ, Gundrak ) along with some of the zones where we cannot accept any quests' perhaps lowering the zone level to allow for play * not merely risky exploration... but I'm not getting my hopes up. Considering that the zone levels of Drustvar & Nazmir were lowered just because of us ( & possibly Spires of Arak, kept at 30 ) I don't see concessions being made for us.
My dream would be to be able to accept quests up to 5 levels higher than our present one, & for some widget being put into the game that allowed us to craft any peice of profession gear at OUR exact level, not the arbitrary crafter's mark pre-sets.
I have no opinions on the 'Dragonflight' leaks, & i'm not excited about it. At all.
I wanted an Azeroth-focused xPac where all the abandoned zones were repaired. The burning chasam in the Barrens, healed. The chunks of Westfall floating, soothed. Thousand Needles, drained & cleansed of Twilight cultists & the Salt-Flats now featuring a mount racing mini-game! The Kaldorei have grown a new Teldrasil on the Ruins of Feathermoon in Feralas. Loch Modan Dam seen rebuilt & the Loch refilled. Deathy's giant dick & balls scrubbed from the Badlands, & Lordearon made into the Forsaken's city ( no more UC... maybe it gets turned into an instance a-lah Gnomer ) & Tiris Fal is remade...
I've heard that Lordaeron is getting a make-over, so is EVersong Woods & the Ghostlands, but... I guess we'll see tomorrow.
