Yes it's me again, the noob who knows nothing

I was just wondering if the only way to get dagger mastery is to buy the expansion pack that includes Assassin, I'm doing the Norn Knuckle fest quests and 1st prize I got is a Gold knuckle that requires +9 Dagger Mastery, which is kinda unfair cause i don't have that class available to me (I will buy Factions, but atm, why have weapons that require class skills that are unavailable, I may be wrong but I've googled and in so far as I know I need factions )
I've been enjoying this game immensely (UT3 gets 5% time, GW's 75%, Other 20% Onlining = Porn, just kidding, I'll prolly buy all Xpansions, I think the 'Knuckies' I speak of are untradeable, it just seems like an unfair prize, is it the same for everyone or is it random?
