Leves in 1.# weren't all that dissimilar to this idea being proposed, where you'd have a high level out doing all the work while 5 low levels still in starting gear would pop leve after level after leve while sitting at camp doing jack all (this is how the RMT then made their gil, by the way). In fact, I'd go so far as to say this is exactly the same. 3 guffs sitting at the entrance reaping the benefits while the high level runs through and clears the dungeon. No, just no. We had our fill of that in 1.#, I'd prefer it if it stayed in 1.#.
