Boy - I used to struggle with this when I was first starting out!
I assume you're still relatively early in the game, because otherwise it really doesn't matter what 2ndary you choose. Once you have "ascended", meaning having completed Hunted! in NF, and you have done the first of the "Building the Base" quests, you can pay 500g and switch your 2nd. Once you have unlocked a 2nd for that character, you can freely change it any time you are in a town or outpost. That said, it is worthwhile to unlock every profession as a potential 2nd, or any time you simply want to try a different D/x build! In short: you're not stuck with whatever you choose as your secondary!
D/N's can be a lot of fun. D/Mo's do quite well. Guildwiki's "PvX" page has lots of builds, rated by readers, and is an excellent source for potential builds. The discussion pages are very good resources to get a feel for why a particular build is good or bad, sometimes due to the difference between PvP and PvE skill usages.
Bottom line: its only a game. It's all about what you have fun doing. Try one out! If you don't like it, you can always change.
(btw: if you have Prophecies and have beaten Augury Rock, there are 2ndary profession quests that are worth 1k exp. This way, you don't have to pay any gold, and actually gain XP, while unlocking additional 2nds!)
