Solo/duo depends entirely on whether you have a friend or generally someone you enjoy playing with, OR whether you are in the mood to play with someone (e.g. too tired after work). So I’ll leave that one out.
As for the rest, this is what I do. Go to this website classicdb DOT ch (I can’t post a link) choose Quests/{Zone Name} and it will list all the quest rewards for you.
You basically just scroll through them and detect the quests that give you good rewards. You then ONLY go for those quests and spend the rest of the time grinding out mobs along the way or if you see them in big packs.
Don’t attack mobs +/- 3 levels (they give LESS xp and the higher level ones will resist your spells). Switch zones all the time. Go for other zones’ quests that give good rewards.
Remember, most quests are useless, they force you to run around for hours. Plus, I am the kind of person who really really dislikes being overly focused on too many objectives. So, at the end of the day I end up farming 50% of the time and the rest is doing important quests.
Now obviously if you come across a quest that is super convenient (close, lots of mobs close to one another), then go for it. But only if it is super convenient.
Also, regarding Blizzard aoe farming, I would stay away from it.
Reasons:
- It forces you to take a specific spec that lowers your PvP / single target potential.
- It is extremely tedious and requires surgical precision.
- Susceptible to RNG.
- You will feel forced to make the best out of every pull, because if you’re not using your AOE’s full potential, the whole approach is a waste.
Instead, just go for a regular Shatter spec. It’s great for PvP and single target, but it still allows you to pull 3-4 mobs whilst grinding. Just round them up, Nova, cast out Flamestrike and Cone of Cold (both will crit), then kite them around the fiery patch whilst spamming Arcane Explosion.
It’s a great break from single target killing, or questing. Plus, you’ll be able to mix it up with questing/grinding.
I believe that by following this approach you’ll get the most out of the game: Some single target grinding, some questing, some aoe grinding. As soon as one becomes boring, you switch to the other.
But the bottom line is: most quests are useless, keep that in mind.
