Statless: To have no points invested in secondary stat. Some use weapons without stat req (weak before VIP weapons came out), some let their needs be carried by gear. An idiot gets it from potential, a wise onw from normal gear stats.
Low stat: To have a few points invested in secondary stat. A cheaper option to statlessness.

That's how I see it, sorry if there was any confussion.

No, I understood you just fine, however, what gear could be worn to possibly have enough DEX to wear lvl 80 thief top/bottom set without using any gear that has a lvl req. below lvl 71? You'd have to get all of your secondary stat from common class equips, such as rings, CHTP, CZak , etc. I suppose if you had an extremely well scrolled CZak, you could pull it off, and a "statless" build would be viable, but, I really doubt it'd make that big of a difference, and it would only really be worth it if you had a nicely scrolled 107 claw or a VIP claw.
