Three man team tips for a noobie

[Geupper]

Hello guys, new here.

Please excuse my English, it's not my first languague.

So I'm running a three man group, one druid tank and two combat rogues, thing is, I'm feeling the 36 lvl bracket too slow, I don't know what I should be doing to level more effficiently my toons, as this is my first time multiboxing.

Also, I don't know if should even be running tank feral and two combats. I picked these classes because they my favorite. What should I do to lvl faster and be more efficient? You think I should respec? Lemme know!
