Well, it's been long enough for people to submit a proposal for the prize and I have already picked one, leveled it to 50 +3, and even moved on to other characters.
Drum-roll, please . . .
And the winner is . . . . @Yomo Kimyata!!!!
Yomo, send me a PM or in-game message to coordinate your PL and prizes
I went with a Dark/Dark Stalker, which ended up having 7 fear powers! Assassin's Eclipse, Touch of Fear, Cloak of Fear, Intimidate, Invoke Panic, Water Spout, and Fear Incarnate. As I was leveling up, the presence pool was helpful in paralyzing one or two critters while I dealt with others. As I gained levels I used those powers less and less. I actually use the fear incarnate power more even though it has worse recharge and endurance because it also has the -tohit that Presence Pool lacks. Pacify also got some use in lieu of Placate, which I skipped. But with the stalker ATOs, neither placate nor pacify is necessary.
The lack of -tohit and high costs of the presence pool powers makes this a pure concept build that works well enough, but I would be much better off taking other powers. If they had - tohit and if I could take either Invoke Panic or Unrelenting with just one power pick I think people might take this pool more often. At a minimum, we should be able to pick intimidate as a first power pick. Many pools allow you to choose any of the first three as your first pick. Come to think of it, I may respec out of Invoke Panic and try Unrelenting. I've never used it at all.
The build was modified using Yomo's as a base. The powers were actually taken in a slightly different order; for example I took combat jumping much earlier. Here's the build:
