Personally, I would be cool with anything, whether it be restarting/merging, etc. But I wouldn't want the entire focus of Dungeoneering to be removed. After all, that is the reason I joined EoE. I only have 100 Dungeoneering myself, and with that focus removed, reaching 120 will be an unthinkable goal, as all of the people that once Dunged in EoE are already level 120 / 200m xp, and no longer care about it. Those are my main thoughts on it.
