Ok - this is in no way an attempt to patronize or ridicule - it's an attempt to educate.

I have a lvl 70 hunter on both alliance side and horde side. (orc and draenei) I solo Strat for money at times (Greater Eternals sell for 20g+ atm) I make the 45 minute Baron timer every time, with somewhere between 5-7 minutes to spare. I kill almost all trash on the way, for the greens which are the real money here.

I'm fairly well equipped, meaning Karazhan/Gruul and badge-gear. Oh, and a few S3/S4 gladiator pieces.

Easiest way to do this: spec 41/20/0 (BM cookiecutter, key elements are imp pet res, imp mend pet, focus and pet dmg talents, and GfTT in MM) - have a lvl 70 bird with max rank screech + growl (no, NOT claw, NEVER claw for aoetanking) and Dive. Imp Mend Pet is godly, as it cleanses a debuff every other tick. If you furthermore have 2 pieces of T5 (I don't) then you will slice through that instance with even more time to spare. run with Aspect of the Viper constantly, mana regen is key aswell.

If you do get the debuff, so you can't eat and it ticks for 150 every 10 seconds... well, here's where those countless stacks of netherweave cloth comes in handy. Whenever you get down to 60% health or so, wait for a tick from the disease, and click bandage. 3400health restored before the next tick. looting corpses for greens reveal quite a few 700-900 healthpots on the way, just chainchug those aswell, since they are worthless to a vendor. Mana should not become an issue, if it does, you're spending mana on in-efficient shots. The only shots you need, are steady and the occasional multi.

Ofc, if you are not diseased, pop the cheap manapots that drop on the way, to keep you going even faster. Spirit Bond can be a boon here, as 2% of max health restored every 10 seconds is enough to counteract the disease by itself. Though I prefer those talent points in focused discipline or whatever it's called.

Lastly, before the baron, outside the slaughterhouse, about 40 or 50 tiny skellies spawn in a stream - drop a Explosive trap before they spawn, let your pet pick them up BEFORE they reach you and the trap, let the pet tank them until your cooldown on traps are ready, then cast Volley on top of the pack, while pulling your pet back to you. as soon as they hit the explosive trap, drop another one and toss 1 holy water/ez-trho dynamite on their heads and the pack is gone. the 2 traps take out about 70% of their health alone.

For Baron, just nuke and multishot when the summoned skellies are close to him. - pop all cooldowns, and misdirect to the bird, and he goes down faster than Balinda in AV.
