A handy little hiding place in Huttball is underneathe the middle ramp at the enemy goal leading up to the rafter.
people comming from the spawn will have a hard time seeing you as your name tag doesn't show up when looking at you from that direction.
A little bonus is that it doesn't count towards the spawn 'kick' timer, unlike standing all the way up against the back wall does.
Alternatively you could also just got a stealther to go there, but It's handy for non stealth classes.
