Woe. and i f***ing hate it
Hour of Twilight is the one I like getting. Takes the least time to complete.
End Time isn't that bad but can get tedious with some mobs.
Well of Eternity is horrible. Too much Role Play, too much waiting, and Too much time spent on Mannoroth. bleh!
Well of Eternity. Even when I DON'T QUEUE FOR A HOT RANDOM.
HoT is my most common. I think they are all wonderful though!
End Time is my favorite, and the most common would be WoE. I love ET coz its so quick, especially if you get Baine and sylvannas/jaina.
Feels like I always get Well of Eternity.
