Is there a term for this type of Party?

[The Legendary Joe]

Focusing on the same monster/group of monsters is a more efficient killing method than being single killing single monsters, also if everyone taps each monster the exp bonus is higher than being alone and getting only the 80% exp from the monster you just killed alone (but you get 80% exp too from the other monsters killed by other members spread on the map)

(or it seems so)

((thats my impression and numbers could be totally wrong as i didnt base on any numerical certainty nor calculations))

Just my way of thinking, several classes tend to get excluded to parties that focus stuffs down due to either being primarily a solo class (Generally thief classes), or their support skills are either too costly or have side effects compared to others (Blacksmith/Alchemist, I suppose monks could have this too).

Having parties where everyone in it isn't bound to sticking together, I think they'd find more use. If people do manage to run into each other, they're more than welcome to assist in killing stuffs but yea.
