- although I have 5 accounts, I have more experience in duos than 5 boxing due to the fact that a few months ago, I knew only voice commander. This is suitable for 2 accounts but no more. Now with keyclone or other similar software, its easy to 5 multibox. Never say thanks enough to those guys,

- with 2 guys compared to 3 or more, you don't have any group xp bonus but if you have just 2 computers like me, no need to play on windowed mode, you have your 2 guys, full screen definition, easy for collection quests, ready to jump to the second keyboard if need be (for rare spells 1 hour cooldown or whatever) so it has its advantages,

- You have many possible combos, even the 2 palas mentionned earlier : one retrib and one healer. Almost any combos is possible (do some research on those forums) except maybe 2 pure melees together like 2 rogues or 2 wawas and even those are playable. Ive tried almost everything and for duos, I prefer to play different classes, except for mages. My 4 favorite combos are (combat rogue, balance druid), (affli lock, disc priest), (feral druid, healadin), (frost mage, fire mage). Im trying soon a (beast hunter, elem shaman). The tremor, mana and agi totem are too good to pass by,

- Also, duos is a good alternative to 5 multiboxing : I have a 5 guys team (druid, pala, 3 mages) for instances but dislike questing with them (2 reasons : collection quests and too many people around me). On the other end, staying all the time in instances is quite boring for me. So, I split them up in 2 teams for questing and level them separately, putting them together from time to time for instances.
