Had some fun playing with Thunderstrike on the test server. It can take a ton of different procs like force feedback, knockback to knockdown, or just all damage. The cool thing is that all the procs can activate on all targets hit in the AoE.
With the long base recharge at 40 seconds, these all fire off pretty regularly. I was testing this on my Time Defender, so the cooldown after Chrono Shift, Hasten, and the global recharge from IOs was pretty short. It can really beef up AoE damage if you might be missing it. Power sink and the resist shield are both useful as well.
The real downside is of this is the loss of one of the other epic pools. Things like Soul Drain, Power Boost, and Power Build Up are very stong, especially on a Time/*. The short cooldown on AoE nukes now also cut into its usefulness, but it was fun to play with anyways!
