Alright, this isn't an exploit or anything, and it's kinda common sense.
Requires:
Good computer (To dual box WoW)
Good internet
Access to a geared 70 dps class (Pref warrior, rogue, feral druid, not something squishy)
Alt that you want to level, preferably a healing class and has to be on a seperate account than the 70
-------------------------------------
So from 55-61 I ran myself through Ramparts, I occasionally went to the 2nd boss, Omor the unscarred, but most of the time I stopped at the first boss, and reset.
I dual boxed my holy priest (55-61) and my warrior (5/5 s3 with s3 wep) and just went up to the first boss all the way to 61
Then I picked up my SP/UB Quests and ran myself through SP from 61-66 getting about 15% a run, skipping every boss but the first boss, and doing a run every 1/2 hour.
TIPS (Some for warrior only):
-Use HoTs (Heals over time), just Alt+Tab, hit Renew or Rejuv on your 70 and tab back in
-Sweeping strikes + Whirlwind + Cleave = Win
-Piercing howl kite when things go bad- just piercing howl, auto run, tab to your healer alt and line up greater heals, tab back in to your 70, piercing howl, tab back in and cast greater heals.
-Use windowed mode on both WoWs (So that tabbing in is instant)
This is not applicable to everyone, and this does require half a brain when it comes to WoW, so only do this if you can be quick at tabbing healing tabbing dpsing and not gimping your dps or healing.
