Well, you're one up on me with emuEQ as I know nothing about those servers ;P I strictly play live boxing & raiding.
Guessing you found it but ADPS = (Attributed/Added) DPS. The major ADPS classes are Enchanter (caster only), Druid (caster only), Shaman (melee only), Bard (melee and caster). Minor ADPS classes would include Rogue (melee), Zerker (melee), BST (melee), Monk (melee), and Ranger (caster/melee). Those classes have limited ADPS contributions compared to the major classes. That is not to say they are worthless though as most ADPS has synergy. There are some stacking issues but that's a whole post in itself.
Again, going with a Rogue main I'd keep your Bard, get a Shaman as your primary healer only (pop a J5 cleric merc if you hit a rough spot; just keep the druid around for ports and utilize campfires for mobilizing), load in two melee DPS, and a tank of your choice. For melee DPS a BST will bring Fero, a backup pet tank, mid-tier attack buffs, and utility such as slow and heals etc,. A Ranger will bring the best attack buffs, a decent backup tank, a short duration emergency mega tank (/wave weaponshield), as well as some patch heals. With a Monk, you get a top notch puller and solid DPS. A zerker... that's an iffy one and unless you having a burning desire to play the class I'd avoid it. This is based solely on the fact that without a high-end weapon and massive support (which this group *is* based around so you'd likely have that part), the class is rather weak. With those components though, zerkers can be a DPS machine*. For a tank... well, I'm going to guess you know enough about each class to make a decision on your preference as they are all viable and the rest of your group composition won't matter as much. IME, the general consensus though is that SK is king of group tanking at this current time; you have a puller, AE aggro, self heals via tap, and more. While the pally is great if you're not using a Cleric, the severe lack of AE abilities really can be frustrating (esp. when boxing if the tank isn't your focus; if you're maining the tank, then it's less of an issue). Warrior will always wear the crown for best defense but none of it is necessary in the group game and you bring no real utililty.
So, my personal choice would be Rogue, Bard, Shaman, BST, whatever DPS not a BST, and SK. If you don't add a Shaman then a BST is gonna be 10X as valuable because of Slow. If you go with Shaman, then BST isn't as important (although they still bring heaps to the group and a little redundancy isn't a big deal). Your other DPS is a toss up; I just wouldn't double up on any class. You could even use a merc in that slot or one of the characters you already have if you don't feel like making something else. The Mage for example is still good DPS but you're not gonna see awesome numbers like those parsing with an Enchanter or Druid; it will still be much more than a DPS merc though.
*You said you have plans to join a raid guild. If this is the case then it's almost guaranteed you'd be able to score your Zerker alt a raid weapon pretty fast (of course depends on the guild's loot rules but weapons are like water in the ocean in recent xpacs). So, it will likely be easy to have a good DPS Zerker if you're willing to hold out for a bit.
Sorry to hog up the thread ;P Hopefully someone else has some opinions!
