Noob Friendly Boxing

Hi there everyone im gonna start the multi boxing proness :D, and even though /follow and blah blah isn't working im wondering what is the most user friendly and a fun class to use in both PvE and PvP situations, I know that I should know anyways, but I havnt played WoW in a good 6-12 months and Ive never multi boxed, so if you could give me some tips on what classes to use ill be very grateful also im gonna be boxing 3v3, or if you its worth it for the extra £ 5v5? but I havnt concluded if I want to invest on a 5 monthly subscription yet :) thank you in advance :D P.S my enter button isn't working so no paragraphs here :)

wrong section can someone move it to the appropriate one? thank you :)

The most basic composition has long been the 4x shaman and a paladin group. 5x balance druids, with two of them dual specced to tank and heal is also popular, although with the moonkin healing glyph for levelling content you might be able to get away with 4x balance + 1 feral even in dungeons.

If you're willing to spend the money I'd do 5 for a month or two, you're probably going to have a rough time with 3 if you want to do dungeons to level and have to pug the other two (as a new boxer).
