Troo was not my first character, or first global handle. He was my third or fourth character.
'Gy' was my first (ss/inv brute), 'Tru' was my second (rad/drk corruptor and favorite to play).
This character, Troo (energy/regen stalker (yep)), just seemed to stumble onto exploits, into bugs, and abused the game mechanics. It became my marketing main and the name other folks used regardless of what character I was playing.
{Homecoming troo version of Troo is level locked at 32 and camps in Siren's hoping for someone to play with}
Similar to ZN below, I might feel a bit obligated for events and such. (blue side makes his hoofs burn)
