Dual 2 rogues! Stabstabdead!

In all seriousness though... I agree that you can probably dual with any 2 classes and make it successful with the right builds and skills.

I also agree with Keri that 2 casters is much more challenging (and expensive) than 2 melee toons or a melee/caster combination.

Have fun!

Personally, it depends what you want the second character to do.
When I first started using a second character it was a druid. I only levelled the druid high enough to be able to heal my warrior to save restos while levelling.
I then made a ranger (when rangers could sit and auto) to give extra dps to my warrior.

Using all three, the druid stayed out of group healing my warrior, the warrior taunted and skill hit, while the ranger just auto hit.
Eventually I managed to include the druid into the mix skill hitting as well, but that was a complete arse to do.

My personal favorite is tri logging ranger, rogue and druid. Pretty solid combo. On a day to day basis, however, I dual log my ranger and rogue. Don't really do much grinding, but if I was, I could simply max light heal on my ranger and max reflex on my rogue.

I first started out slow by using bandage wounds to follow my toon places. Slowly moved into trying pvp combat with 2 devices (damn warriors). Then tried out using an xp lix, takes some time to get used to it but if you got the money and your elbows don't hurt I say go for it. Very handy in an end game clan where these bosses take 40+ to kill.

Mage/ Druid. Rogue/ Druid.

I tried Druid/ Druid. One was dps other support and had fun.

Genious!
I really wanna try that now haha

I have recently been using my mage to help lvl my rogue. My mage is 190 atm and my rogue is 165 now. At first I could not manage all the buttons at once, but I am much better at it now. I am thinking about getting my rogue to 190, and then I can dual level them the next time the cap is raised. Mage/Rogue is a combination that I do not think was mentioned. There are some definate survivability issues (as compared to a combo with a ranger of druid to heal), but a mage with fire/pierce lures and a rogue with all fire damage gear can be a potent combination.

Personally I think the most effective combo for levelling is a Druid - DPS. When I level I go Druid (Support) and Warrior (DPS). That combination is also helpful for soloing bosses but the warrior needs to either be a hybrid or Tank. Either way with the right gear you can make anything work.

In regards to the screen. Personally I would put the character you need to move more, cast spells on more, tank mobs on etc as the bigger screen, cause realistically all your druid does is press the heal button. Navigation wise, can either control via the way Bitey Described, or you can cast a skill on a player that is travelling out of range. (In Game 6 Metres)

It's kind of surprising no one has mentioned multiple same type combos like rogue rogue rogue. It's hard to have too much rogue - perhaps impossible. Haven't tried this at high level but its unbelievable at leveling with enough regen/sigils. It isn't as good for most bosses unless you don't mind spending lots of plat items.

Also i regularly steer and move four toons simultaneously and manually. Guess it helps I was duo log before the game came out on other mmos. I like to arrange my devices 2x2 and use the only move straight ahead method. I use my thumb and index finger on my left hand to move the joysticks while my middle finger switches between steering and on my right hand my thumb and middle finger for moving and my index finger for steering. I need to use the last knucke on my right middle finger to steer the lower device because my fingernail gets in the way.

It helps a lot to navigate the same path with all of them I can do the sewers from ley to necro only stopping 1-3 times to regroup and don't get stuck on walls much so it can be done manually.

I also use a 5th device - an iPad - above the 2x2 and use my druid on it since it's easier to target things on the screen, read and type.

Once you start practicing tri and quad driving toons manually duo becomes extremely easy to the point I have no problems driving each in different cramped areas.

A really good combination is Rogue/Ranger. I find this combination works really well if you max bolas, and light heal on your ranger and fast reflex on your rogue. Every mob the ranger just bolased and starts attacking while the rogue gives the ranger a second or two to get enough aggro so that he wont be targeted for the rest of the kill. You can also basically solo a lot of bosses with this combo (when rogue gets aggro, he just runs out of aggro range then comes back). I also dual a Mage / Rogue. This combination is very effective. I maxed assassins lure on mage and rest dps skills, and on rogue I went full dps. Its very effective because the mobs die really fast with the rogues high autos and the mages nukes.

To move i generally do what Bitey said.

One device on top of the other, and my left index controls my top char (usually my rogue), and my left thumb controls the joy stick on my bottom device. I use my right hand to adjust the camera and whenever there is a mob, i cast assassins lure on it while shadow striking it with my rogue. Works really well.

Have fun dual devicing!

To Plus3 who said a 5th device holy moly. Tri I could handle but 5... I am convinced you play with your pinky toes. That your really Chuck Norris and has a fist for a chin :/
Yes I been doing mage/ rogue now. My rogue doesn't have rejuv items atm so the e boost been a kicker. 80's atm but fun with mages.

I'd say the best idea is to have one character fully supporting the other, and the est way to do that is have a druid and a rogue. That's how I've been doing it and have found it to be the most effective and fun way to play. To each their own though.
