Any 80-90 boost guide? No questing.

Cata instances sucked, they were too hard even for single players (too hard meaning the general population and pugs wiped on everything). The trash hits hard and the mechanics are important to the point where they cause wipes. That'd be a slow and painful way to level.

My intention was to start learning how to play my teams in Cata instances so I tried BRC ... didn't go well. Throne of Tides ... nightmare .. worth taking the time to complete Cata instances ... ?

Not worth your time. MoP instances and heroics are considerably easier and smoother than Cata ones were. Some of the cata instances are the most annoying thing since Shadow Labs in BC and UBRS in vanilla.

80-85 xp req was nerfed and cata quests are generally not that painful, you can do a level in 2-3 hours, 4-5 if you're a slower quester. This'll also get you 2-3k gold per toon for your flying and such. Then 85-90 questing is 5-10k per toon and 430+ gear the minute you hit 90. Your other viable options at this point are stormstout brewery monkey farming (a 15-20 hour grind, hundreds of resets), or PVP which outside of IOC/AV week is slow and painful also, unless you do premades.
