This is a build which does fantastic in a team. If there's a large spawn, I'll pop in via Burst of Speed and use my PBAoEs: Atomic Blast, Irradiate, and Dragon's Tail, along with more Burst of Speed. If there's a single hard target, I'll get into melee and use Proton Volley (when Instasnipe is up*), Cosmic Burst and Eagle's Claw. When I need to stay at range, I'll hit single targets with Proton Volley, Cosmic Burst and X-Ray Beam.
*Due to how Reach for the Limit works, Instasnipe is often up, but not all the time. If there's enough team +ToHit around me, Instasnipe is up too.
Since I have Inner Will and Defiance, I don't really need Clarion. Since I have Reaction Time, as long a I stay in melee, I don't run out of End very often. So I picked up Barrier as my Destiny for more survivability - this works well.
I don't use Energy Gauntlet - it's only there to enable getting Force Barrier (a power which really helps with survivability).
Sadly, I don't use Ki Push very often, but it is there if I want the fun or need to use it.
