Begging the devs to fix a problem created by the community will not work. Everyone wants to be a dps its the same in every game and will not change, i can tell you as a tank there is literally nothing they can offer me to get me to rerun lower dungeons again. If i do it its as a favor to a friend or guild mate, your only solution is to ask to be carried in by a tank or healer friend or someone who happens to be lvling at the same time. I capped ninja at the peak of its popularity so i have seen it at its worse, since everyone i knew was doing the same grouping was pointless so i just did fates and leves while queued. The endeavor wasn't important enough to me to bother people for help but it is the only advice i can give you since S.E. will do nothing for it.
