no. but i could be. is that how you do it?
Well. First off, class wise, arms warriors are still viable (with the addition of fury warriors), as the one you linked. But the classes to watch out for are rogues, druids (specifically ferals), BM monks, shadow priests (as always), and ret paladins.
Hunters and prot specs have been nerfed to the ground. But hunters are still viable if played correctly.
Pvp (along with the new arena feature) is now 20-29
Gearing wise:
all gear except gear that is over ilvl 34, will be scaled to ilvl 34. In many cases, low ilvl greens and blues may scale higher than others above it.
See here.
Some of the BFD quests are no longer and the dungeon has been revamped. Many of the quest rewards are grandfathered. The remaining quests have the same rewards as the previous iterations, and can be completed even if you have the same rewards as before.
All boa is to be included into an account wide boa tab, allowing players to easily create boa on any toon once unlocked. Log into each toon with old boa to unlock them if you have any. Starter accounts can use this feature now.
Starter accounts who are also linked with subscribbed accounts can now use guild heirlooms if the paid account has added them to the boa tab by logging into each toon on the subbed account.
Necklace heirlooms are a newly added feature and can only be obtained through a subbed account and then linked to a starter account. Given you have the starter under the same email as the subbed account.
All heirlooms can be purchased with a relatively low amount of gold as opposed to justice points/honor in mop. Guild heirlooms still require rep to purchase. The honor boa vendor still sells pvp boa, but the prices have been more than cut in half. And pvp boa mostly favors haste, as opposed to their pve counterparts which rely mostly on crit.
Bonus armor gives additional attack power to tank specs.
This achievement below has been added. Once a player collects a total of 35 boa, which is possible unlinked, it unlocks this and grants the person an account wide mount capable of use at level 1 (apprentice riding speed)

Veteran accounts:
This new feature adds another type of twink to the 20-29 playlist, and has been very favorable over the past couple of months. Veteran accounts are basically paid accounts that have ended their subscription. The toons that are over level 20 have been locked and the toons that are level 20 or under are playable. But players must be cautious as to not accidentally level any twinks below level 20, as experience is on until the player reaches 20, much like starter edition(with similar restrictions). The one major difference is the fact that you can twink out a level 20 similar to that of a p2p, max professions, and be in a guild. But most of this has to be done before unsubscribing. Once unsubscribed, that player can play this maxed out level 20 twink without having to pay again, unless he decides to resub and make another twink, make adjustments, or simply play at endgame.
Examples.
