The Bard PP Voice of Thunder has an absurdly powerful level 11 encounter power, Rolling Echo.
Hit: 2d6 + Charisma modifier thunder damage, and you push the target 1 square. Before you take any actions during your next turn, you can repeat the attack as a free action.
Since the repeat rider is on the Hit: line, this means that regardless of whether you think "repeat the attack" means "attack power" or "attack from this power", it will trigger again on your next turn when you hit with it, meaning you get a massive free action, ally-friendly attack power every round as long as there are still enemies around to nuke with it.
Honestly, the only key piece here is Rolling Echo. From there, it's a short matter of taking a Sorcerer and stapling as much thunder damage support to them as humanly possible, and it turns out that's quite a bit.
Just doing a quick proof of concept here, but I'm pretty sure it's close to maximum on damage for its level. We are a pixie, which gives us two big benefits. First, it lets us ride our elemental companion the Storm Talon everywhere, and second, it means we get the cheapest +item bonus to damage item in the game.
On round 1, we use Pixie Dust as a move action and command our elemental companion to fly, flying up to 11 squares to approach. We then use Rolling Echo as a standard action, grouping as many enemies as possible. If we have an action point available, we follow up with Explosive Pyre, and hopefully everything dies from that. If not, we end our turn.
Every turn after this, we start by using Rolling Echo as a close burst 3 originating anywhere within 2 squares of us, group up all the enemies we can, and follow up with another standard action thunder attack. On the off chance we run out of AoEs in some extremely large battle, start charging with Ensorcelled Blade. It's all pretty easy.

First off, let me note that I in no way agree with the system the DPR kings thread uses to rate AoE attacks, as it's severely overvalued. But hey, it's their choice.
Rolling Thunder is a 7x7 friendly attack, which according to their arbitrary chart has a multiplier value of 3.8124. However, it's also a 3x3 friendly attack at a bonus, so we need to break it into two chunks to evaluate.
Rolling Echo (3x3): LVL+7 vs. NAD, 2d6+30=37 (hit), 42+3d6=52.5 (crit). 2.178(.75(37)+.05(52.5))=66.15675
Rolling Echo (7x7-3x3):LVL+5 vs. NAD, 2d6+30=37 (hit), 42+3d6=52.5 (crit). (3.8124-2.178)(.65(37)+.05(52.5))=43.59762
Rolling Echo total per round: 66.16+43.60= 109.8 damage.
After repeating this process a bunch of times for all my other encounter powers and then Charging with Ensorcelled Blade once they run out, we reach our round-by-round DPR:
