Fighting in groups

First off I just want to say hello everyone, and I hope that anything I add helps someone in someway.

Group Dynamix
I am writting this because of all the crap groups that i have had lately. Not that it is because of other people playing with me, or myself. I believe it to be a lack of knowledge playing a roll in a group.

Building a group:

What do you need to build a group. Well, that is simple. First thing is to look at what quest are you doing. Does the quest have runes that need Int., or Wis to open, locked doors and chests and traps. Simple questions like that to decide what character classes to bring along.

Now that you have an idea of what you are up against it is time to start gathering people for your group: 1: Tank

Fighter: Just as the name suggests, you are a fighting machine. Your goal is to take on the main assult on your group. Fighter has good armor and made to melee.

Barb: Another tank, but unlike a fighter a Barb has less armor, but more hp and able to melee with the best of them.

Paladin: Nice all around tank. What more can I say here, you can heal at lvl 4 and use the heaviest of armors.

2: Healer(many can fill this roll, it just depends on what you have in your group)

Cleric: This is a no brainer(can heal everyone, WF take half healing)

Bard: Makes a good back up healer

Wizard/Sorc: Make good healers if you have Warforged

3: Support(This is where all the other classes shine)

Rogue: Nice to have in a group, finds secret doors, disarms traps and unlocks everyhing that the DM's let you unlock. Not to mention nice for ranged dmg or getting behind an enemy for a sneak attack(sneak attack is nice, i have lvl 5 rogue and currently my sneak attack is at 3d6)

Ranger: Good for ranged dmg, finding some hidden doors(if no rogue around) and scouting ahead.

Bard: Like I said already good for back-up heals, but also good buffs and croud controls. Bards are just the jack of all trades, master of none(sorry, can't remember where I herd that line)

4: Casters

Wizard: A great class to have around because they can open some of those pesky runes that require Int to open. There main job is blasting mobs of enemies or taking out that 1 bas ass boss. Also great at buffing up the group.

Sorc.: Like a Wizard, this class is made for blasting mobs and taking down that boss. Unlike Wizards they don't have the ammount of spells to choose from, but have many more SP's and cast faster than a Wizard.
