Done my homework but still have a few questions

depends what your goals are.

3 shamans work well, they have good dps and are easy to set up.
If you try and do only dps you'll have long dungeon queues. 2dps+1heal will be much quicker, and is very viable with 3 shaman as well, but you'll definitely need a couple more players to do instances correctly.

If you want to do something a bit challenging, then maybe do a full tank+dps+healer group.
maybe a paladin + 2 shaman, or something like that.

all instances at lower levels are fun to do, just use the Looking for group tool and you'll be ported there as soon as you can.
Most of the fights in those instances are very simple, and can be done with not much hassle

What im looking for tho, would be like solo, for somepart, but id like the option of instances to

ya well i really only want to play two charectors, as i really dont want that chalenging, i figure if i roll 3 shamans, i can have two ranged DPS(both with the exact same lay out) so then im just healing and doing dmg, instead of trying to run all 3 charectors, and i also plan to make the one thats the healer, duel stated to DPS aswell, that way if im playing with my friend who heals i only have to worry about one roll

what i want is to only have to watch one screen am i able to use this for all my damage on my two dps while im healing with the third like

/target alkamino
/assist
/cast _________

is this gonna work? or im i going to need to physcially point and click for area of effect casts?
