As usual, we'll start right off with answering your questions. If you have a question you want answered in a future edition of The Queue, just leave your question in the comments section below and we'll try to get to you next time!
What is the minimum required enchanting skill to disenchant epics from Naxxramas? It's unlikely that we will need to for a while, but it would be handy to know!
You only need 375 Enchanting. If you capped Enchanting off in The Burning Crusade, you're set straight to epics.
How much gold do the level 80 dailies give you? Are there even level 80 specific dailies, or do you just gain more gold from the existing ones you find as you level due to no longer gaining the xp from them? I know there were heroic / regular dungeon dailies mentioned recently, but it was never actually mentioned how much or what they offer in way of reward.
It sort of depends on the daily. If it's more difficult, you'll get more gold. Sort of how when you're leveling, a group quest gives you far more XP than a solo quest. The typical solo level 80 daily quest will net you a bit over 13 gold at level 80.
The Dungeon Daily and Heroic Daily gives extra gold (in the area of 30g total per quest rather than 13g), and also an item. The Dungeon Daily gives you a token that you can use to increase your reputation with the Kirin Tor, Wyrmrest Accord, the Argent Crusade or the Ebon Blade by 250. The Heroic Daily gives you two extra Emblems of Heroism.
Daily quests that open up before level 80ish will give you less gold depending on their level. For example, the quest in which you steal babies for a walrusman in the Dragonblight only give 5 gold at top level. Those are still worth doing for the reputation, though. They give a fair amount of that.
By way of questing through the Fjord and part of the Dragonblight, I've come across three quest rewards as a tank. Not upgrades or sidegrades or downgrades, just rewards, period. Meanwhile, my healing off-set is getting really good, with two blue trinkets, new gear in pretty much every slot, etc etc. Does this situation get better in the last half of the Dragonblight and on, or should I just respec?
As you get closer to 80 you'll start seeing more tanking rewards. There aren't a whole lot of tanking rewards early on because most people probably wouldn't even take them, it's not considered 'leveling gear.' Even tanks would throw on some extra DPS gear while soloing to get the most out of their Shield Slams or whatever. It's a bit of a problem when it comes to tanking dungeons if you didn't start Wrath with good tank gear, but if you find yourself getting endlessly gibbed you could commission a Blacksmith to make you a set of Tempered Saronite gear. Expensive, but it's something.
...although I suppose you could be a Druid as well, and not necessarily a Paladin, which was my gut instinct when you said 'healing off-set.' If you're a Druid, generic leather with stamina, strength and agility will be just perfectly fine and dandy until 80. Nothing hits super hard in pre-Heroic dungeons. As long as you have enough HP to not die, you're okay. Once you near level 80, you'll start coming across a lot more real tanking gear.
