- New Character Models-this change is purely subjective. I'm not wild about the changes and might revert mine to the old models for awhile. It might also be better for my computer to be on the old, lower pixel, models. I was in beta and honestly wasn't really thrilled with the new look or movements. But they might grow on me.
- Class Changes- so many things here. As an altoholic, and as someone with at least 2 of each class at level 90(one each Horde and Alliance), it's going to take time to get used to all of the changed. There is a lot of ability pruning, which in some cases is a good thing. There is one change that really grinds my gears at this point-taking away my Druid cheetah form when I choose to use it! What that means it "travel form" is one button-aquatic, land and flight. So that means if I am in an area with flight enabled such as anywhere on Azeroth, I can't just run around in cheetah(I HATE stag form), can't run back and forth from mailbox to auction house, can't do archaeology in cheetah, can't just run around where ever I want in my beautiful, beloved little cheetah! My first main was a Druid, and I ran that little cheetah until nearly level 60 because I couldn't afford a mount way back then. I LOVE MY CHEETAH! DON'T TAKE IT AWAY! (sorry for the rant)
- Guild Levels Gone- as a soloer, this one doesn't affect me as much, or it doesn't matter as much-and it's ultimately a good thing. Yes on my 4 main realms, 3 have personal guilds. One has managed to get to 25, the other two are at around 15. This change means all guilded characters get all of the benefits that level 25 guilds used to have. And all of my unguilded characters? The perks aren't worth it for me to attempt to find some place with strangers to hang around.
- Blasted Lands Quests- the new expansion event, sending us to the Dark Portal to fight off the Iron Horde invasion. Looks rather easy to do. At this point I am pretty sure that the achievement title, ...the Iron Vanguard, is account wide, so I won't have to do the quests 43 times! I hope that is the case. However, the mini pet that comes with it apparently comes in different breeds-and if you are into pet battles, that could mean doing the quests numerous times in order to get the "right ones". Plus, there is a Bronze Whelpling that drops from the mobs in the area, so I am expecting much farming in the weeks to come.
- Stat Squish-this might be one that throws the casual player off if they haven't bothered to read anything at all in the last few months. On beta I barely noticed the number difference. BONUS thing here is there will be a new mechanic added to older raids/dungeons(lower than 85-?-)that will make them basically a steam roll for those at level 90 or higher. I really hope that means I can send all alts to Zul'Gurub to farm those mounts each day!
- Stat Changes- reforging is gone. For someone who didn't raid, I never bothered with reforging, so I really don't care. The stats "hit, expertise, dodge and parry" are gone. Since I never bothered to do the whole min/max thing, these don't mean much. But this means the annoying part of mobs dodging you hits is gone! Excellent!
- Auction House Merger- Horde and Alliance auction houses as one, dogs and cats living together. Not really sure how this will be. Glut of resources to compete with though more buyers. But no more sneaky selling things to your cross faction alts. Hoping for cross faction mail in the future.
- Justice and Valor Points gone- never gathered many of these, so just send me the money from all the valor I gained doing dailies in Pandaria!
- Toy Box -might be biggest change of all! All those fun items taking up valuable bank and bag space moved to toy box! Account wide so ALL my characters can use the Orb of Deception or other fun things! I can't wait for this!
- Reagent Bank -a whole other bank page JUST for reagents. Costs 100g, which is pittance. Auto-upload all mats to that page, goodbye inscription, engineering, mining bags. For characters without access to a personal guild bank, this is very helpful. Not to mention most mats changing from 20 per stack to 200 per stack. Oh yes.
- Void Storage- a whole 'nother page for Void Storage. Hoarders and transmog collectors rejoice!
So those are the main changes. There are other minor UI changes, such as adding a number to cooldowns(goodbye OmniCC), more info on Mount page plus a "favorite mount" option with button, quest log and map merger, change to some older dungeons-RFC, RFK and BFD, and all those nasty Kor'Kron guards are gone from Orgrimmar and Undercity. There are quite a few other changes to current raids and a new level 90 dungeon, but as a soloer those do not affect me.
Now let's see how soon we actually get to play!
