Warrior should be a go-to choice for everyone who wants to get into the end game. Protection Warriors in Classic WoW were considered as one of the best tanks, Fury talent build was a great option for DPS while Arms were dominating PvP environment. However, Warriors’ strength relies on the character’s gear, which means that you might need to put some hours into finding the right items for your class. It is also worth mentioning, that Warrior might be one of the hardest classes to level up in World of Warcraft: Classic but rest assured, if you’ll manage to hit the level cap and find suitable gear, Warrior is one of the strongest classes in the game.
My own experience with the WoW Classic beta in the past few days has reaffirmed my longstanding suspicion that the MMO genre ran out of gas entirely too soon. The motifs of progression, classes, and challenging raid content have successfully disseminated into other genres at this point but these concepts are much more interesting when applied to a dynamic, communal space. I hope that both fans and developers will discover that World of Warcraft Classic has lessons left to teach when it releases on August 27th.
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.
Balance: Moonkin Aura - Starsurge grants 4% spell critical strike chance to 8 allies within 40 yards for 18 sec, stacking up to 3 times. Feral: Leader of the Pack - While in Cat Form, you increase the melee and ranged critical chance of raid members within 40 yards by 5%. Leader of the Pack also causes affected targets to heal themselves for 4% of their maximum health when they critically hit with a melee or ranged attack. The healing effect cannot occur more than once every 6 sec. Guardian: Sharpened Claws - Maul increases the damage done by your Swipe and Thrash by 25% for 6 sec. Restoration: Overgrowth - Instantly applies Lifebloom, Rejuvenation, Wild Growth, and Regrowth's heal over time effect to the target. Hunter
Note: My goal here was to create a comprehensive list of everything you'd need in order to learn to play any class (from Level 1 to Naxxramas)—meaning I am only including class-specific resources here (so no profession guides, general leveling guides, etc). Teeb's Resource list is much broader in scope, and I highly recommend you take advantage of it (as it contains a plethora of non-class specific resources as well). If you're not aware, Teeb is also responsible for the Race & Class Comparison Tool, Dungeon Tier Sets Gallery, and a huge variety of other insanely useful resources.
So, if you happen to have two good 1h weapons, and are Fury specced, don't be afraid to try out dual wielding. Some people swear by it, and I can see why. Getting miss/parry with 2h weapon is cancer, and having two weapon swings for two different chances at crit, can really help smooth out your damage and make it less random. If you're still skeptical, I'd suggest trying it out once you get Thrash Blade, or if you happen to have a Flurry Axe. With really sick 1h weapons, dual-wielding can definitely feel great.
As many of you know, leveling a Warrior in Classic is not easy - it’s almost like playing the game on hard mode. Despite having low mobility, low sustain, and the highest gear dependance in the game, Warriors are by far the most played class in Vanilla. There is a sort of masochistic appeal to leveling the hardest class in the game. To some, this epic challenge provides the purest Vanilla experience, and watching an expert pilot this class with finesse is like watching an artist at work.
That's not to say that everyone has an unrealistic vision of what vanilla WoW was like. There were already plenty of people on the WoW Classic forums pointing out that perceived bugs are just recreations of the original game. And as noted before, a flaw to one player is a key component of the original positive experience to another. WoW Classic will surely please plenty of purists in spades. But this goes to show that it won't be for everyone who has fond memories of the game circa 2006.
