If you want the items for the novelty factor, get them now (before you've done a whole bunch of stuff and grown attached etc).


Apart from novelty...they were designed back when R1-10 took a few hours, so they were very useful.

R1-10 now takes about 45-60 minutes, so apart from the first hour(ish) you spend on any class, an onion helm is not an item that's gonna set you apart from other players.
