I saw him once he's not really top player he just top player sword at fg server because fg server has low class level of glad gameplay, otherwise there is no more real glad players anymore, i have nothing about bunny he looks good, but i agree with your idea for me it must be more balanced because Shotguns outplay is more hard to play than glad ( more skills,more tactics....)
and it's hard to be in streak of killing without any death
So i hope they make it more balanced
