I actually would like any kind of thief related event, even if its just exp thief :P I remember the fun I had chasing those thieves running away from us. Maybe STS can make eggxavier spawn only in harder elite maps so as to not "crash the market", like how the anti-set thief spawned only at bosses in elites. Imagine trying to kill the thief in mauso lol. Start chasing him and then BAMMM CURSED!!
