Blizz stated in a watercooler that they're using the 1.12 database as a starting point. I don't think it's a stretch for people to assume that most game features and mechanics will be in their 1.12 state. The kind of stuff I would expect to see reverted would be numerous AV changes, but I seriously doubt class mechanics are going to be reverted. I'd be surprised if the threat changes that ruin pre-naxx encounters are reverted.
In terms of what the World of Warcraft Classic Best Classes are, Warrior and Priest stand out almost instantly. This is partly due to the fact that Protection Warrior is the only viable Tank Class in WoW Vanilla Patch 1.12. Both the Proc Warrior and Priest are required for Raids and when combined in a PVP setting can be a fierce combo on the battlegrounds.
Nov 15 We ordered vanilla not vanilla with sprinkles 1. Sharding/Phasing was not a part of the classic experience. The launch surge and often times overwhleming population fighting over quest mobs and loot was impactful on a human level which brought people together to make parties so they weren't fighting or made people bitter rivals. And that ten minutes you spent competing with people to loot that bucket before it despawned for another few minutes was intense. 2. Loot trading was not a part of the classic experience. Ninja looting was a real thing, a crime you could commit which united the community up in arms against you, blacklisting you. That's a feature for modern WoW, not genuine classic. This is a recreation. Not a remaster. Not reforged. We ordered vanilla, not vanilla with sprinkles on it with modern hand holding baby coddling streamlined bogus. That's more suited to your modern WoW playerbase, not the millions waiting patiently for the game they knew and loved over a decade ago. I don't want to sound like an entitled brat, but when you advertise a product, don't change it behind the scenes. Please Blizzard, don't add these things. They kill aspects of what made classic wow such a special phenomenon that rallied people to make private servers in its honor. I'll go play one if this isn't authentic, because those unofficial servers would be more authentic.Rhystael95 Nov 15
...but, in my experiences, I found dual wielding to be fine. But only if you're Fury. I found that having two weapon swings meant having twice as many chances to crit, which led to lots more Flurry procs. At level 50 with two blue 1h swords, my kill speed was just about the same as when I used an epic 2h axe. And I wasn't even specced into the offhand damage talent. If I got a good string of crits, I could smack mobs down in 15-20 seconds, and easily hit Bloodthirst every time it came off CD.
The primary goal of Conflict and Strife is to provide an interesting choice in PvP by allowing access to an extra PvP Talent. It’s not necessarily going to be a strong option for PvE. The acquisition of this Essence is via PvP, and is totally optional for PvE-focused players. While there may be interesting PvE uses for some of the choices, it is not expected to be a strong competitor on usual PvE criteria (like total throughput) on every spec.
