When you play by the actual rules, D6 Jedi aren't actually that great until they are fossil characters. In fact, if you're starting from a normal character generation, they're gold bricks for the bulk of a campaign.
The reason they're OP on Mushes is because of poorly thought out house rules like they don't take the attribute hit for their initial force skills or have to seek out teachers for powers. That and straight up CP for +noms is a terrible idea, the system was designed so that an adventure or TP would be worth 3-5 cp rather than the hordes most mushes rain on PCs.
