this is a good point, and a problem with most of the npc thieves in SoA. In my opinion you should never dual-class from a thief, only ever dual-class to thief (if you want part thief). The reason for this is that you never want a thief to stop gaining levels. Other classes are useful to have a few low levels in, but thieves are never 'complete'. There are always more skills you will want. with 7 skills that you will want all over 100 to be really effective, and gaining a maximum of 25 skill points per level (plus a few points on creation), you will probably be level ~27 before all your skills are up to the point you want them. if you're part mage, you won't want ring/gauntlet spots taken up with thief enhancing items. Generally I would say keep all thieves pure class, unless you start with a few levels of fighter... or else multiclass, but this will mean no thief kits and slow level-ups with a full party of 6.
