I agree with Yeargdribble

There really isn't a "Perfect" set up that always works. And even if there were a "perfect" party set up that doesn't guarantee that the people in the party know what they should be doin'.

I usually just check out the feel of the party and if it doesn't work then it doesn't work. I disband and move on.

I have been encountering alot of noobish groups who just build a party with their mates and disregard the fact there isn't a healer or DD ...
or that the lvl's in the party are spread out to about 5 or 6 ...

I am not trying to put anyone down because i am still pretty new to XI and i make mistakes to.

But sometimes those partys that you think "Holy cow this is going to be a big disaster!" turn out to be funner and more challenging ... sometimes that lil' voice of the tiny man inside your head was right .

I don't know ... i just try to have fun with it regardless
