IMO I think were looking at something liek this
(X's mean fill in the blank with the best class to support)
Mo/E - FULL HEALING / Earth magic (ward of melee, armor of earth)
Mo/X - Full healing / Fillintheblank
E/Mo - FULL PROTECTION MONK + air magic or earth magic, even fire.
E/N - FULL FIRE ELE + CURSES 2 Skills needed for this charector.
CHILABINS and PLAGUE SENDING (very, very powerful skills when used together)
Me/Mo - Domination build w/ minor healing sub-spec to help healers if trained
Me/X - Domination Build / (I forgot what the other build is)
W/Mo - Either Sword or Axe spec'd, high damage output spec.
W/N - Sword or Axe, high damage output spec.
[optional: will take necro elite of lingering curse, where main target only has half health gained from healing spells, would be a major manaburn for other healers and speed up the killing process.]
note. this is a 35 mana spell put together,
Little explantion of how this works. 2 Warriors train 1 monk.
For 2 monks, 1 mesmer will get on the train, the other on the 2nd monk, shutting them down = easy death.
For 3 monks, 1 mesmer on each monk, train on a seperate monk, therfor the trained monk can only heal himself.
For 4 monks(rare and worthless spec most of the time), Warriors train 1 monk, mesmers on their own monk, and the E's team up on the 4th.
Thats how the w/me's would work together, of course the monk's(e/mo included) would focus on healing, but you ask yourself, whats the last E for? Simple, Meteor Shower and Firestorm and plague sending, thoose 3 spells together can dominate a large group of people FAST (ever wonder how everyone on the team gets poisoned so fast and is almost at half health mid game but only 1 train and no E's on the other team?) , If you drop even a single meteor on any healer, his chances of dieing rise exponentially, because he cant heal himself for 4 seconds, even better if you drop it on the NON-Trained healer, then the trained healer is forced to heal himself, which is not easy. Plus, most monks dont have poison cure, I know I dont

All suggestions welcome, and im sure this is subject to some change, if we all agree on a spec, maybe we can start fielding 8 mans soon as we have enough 20's.
I know personally I can play either Mo/E E/N or Me
