ok i got 3 Elites and 3 Rares on the quest and its only at 52%? who's idea was it not to add bonuses to quests on this seasonal quests?
They messed up and it's "fixed internally." I assume for next year only. https://forums.daybreakgames.com/eq/index.php?threads/overseer-quests-for-stone-cold-summer.292355/ I have a newish-to-overseer character who still hasn't gotten a success on that mission. Only has Rallos as the option for slot 1 and he got a 36 hour timeout on the last failure. Quite an experience.
Until they patch it (which probably won't be in time for this year's event), you can manually assign agents without using all elites and get basically the same success chance, since there are no beneficial/detrimental attributes associated with each slot. It'll keep you from wasting your elites on this crap.
