Twice I saw this. The second time was a male and female character outfitted as GLs (with Greek Phis as chest letter, etc.) floating, posing under Atlas one evening.
They had bubble powers with a whole body bubble, easy enough. However they also had a little bubble around their "ring hand". I could never figure out this power.
Was it a secret power left over from a dev GL experiment? Was it generally available as a secret slash command? Or did one have to be a dev level account?
The very existence of the taunting tank irritates, for it requires idiotic AI that obeys the taunt.
