Real busy sitting in queues, trying to level, etc. Will get some updated info once things calm down a bit, will get up a Glad guide too.
For now, honestly it just comes down to level up - gear up with whatever the highest ilvl crap you can get (Heroic 5m + WF + socket ideally). Stats don't really matter as much as highest ilvl and nobody can even make the best gems/enchants yet, so min/maxing that is still a little ways off.
For Arms: Get crit, avoid Mastery like the plague (unless you want to make a second single target only set
), little bit of Haste you need should come incidentally.
For Fury: Get crit and Haste (very unlikely you'll hit the early soft cap, if you do, you can start swapping gear around), no stat is really bad like Arms Mastery.
For Glad: Get Bonus Armor shit and a shield.
Also, PSA: Glyph of Executor is bugged, it grants 30 rage before using rage on execute. It's still not bad for leveling though and works with Sudden Death.
