Once more, you are not getting what I mean by using the favor flag. I do not know if this is because the way I describe my proposal is too vague or too complex; if it is, I apologize. Allow me to put some of your concerns to rest.
Power Leveling Favor
Quest's Favor Amount =/= Suggested CoV amount dropped.
A quest could give 4 favor or 400 favor, it has no effect whatsoever on how many CoV is given.
It doesn't matter what Epic quest you do, just as long as you do it. If CoV have a universal drop rate, then I don't see the difference between doing 4 quests with the "best rates," vs. 4 of any other epic quests - it would still be the same amount of CoV. If Turbine didn't go with a universal spread, perhaps they could offer more drops to the non-uber quests.
Group Favor =/= CoV drops.
Total Favor =/= CoV drops.
I don't know why you think a specific group affects anything, when I keep saying "CoV drops from any quest" Claiming Yugoloth favor being thin has no effect on CoV dropping from any epic quest completion.
I am not saying build X favor with a group and get commendations.
I am not saying build X total favor and get commendations.
I only suggest that when you complete a quest on E-Normal, favor flag turns on for E-Normal favor rewards. A similar, second flag can turn on to drop E-normal CoV amount. Originally I was suggesting the same flag, but EllisDee37 pointed out the favor flag does not reset with Epic TR.
