In-game, my Tanker's Burst says it takes Universal Damage, Taunt, PBAoE, and AT sets. And yes, it accepts Stun enhancements, but not Stun sets.
Same thing on my Stalker's Burst, minus Taunt.
Thanks for taking the time to verify that for me. 
...and /bugged.
Apparently, I play "City of Shakespeare"

Clearly the dev's dont like the pbaoe footstomp force feedback fun. My kin would love to have the recharge bursts. 
Wanted to see if anyone could verify that a bug I'm seeing in Mids is rooted in an in-game bug:
Kinetic Melee's Burst says it does KD/KB but in Mid's (and in City of Data); it doesn't allow for KB/KB set slotting... instead, its accepting Stun Enhancements (but not Stun Sets)?
