So, Warrior to tank and 1-2x Paly for Heals, along with Monk for DPS and Cleric for giggles and buffs?

Would a ranger be a good 5th box to just set and forget? or would another class be better for that? or a bard to buff the melee dps?

Ive not played in a really long time, I have a 70 Warrior, Mage, Cleric, Monk and im not sure how to proceed, or if i should roll different toons all together. Warrior and Cleric ill be sticking with, not sure what else i need. I really dont wanna go past 4 boxes, so what would be good to go with a Warrior / Cleric to progress with?
