Use them guys! =D
It's better to plan out your build at level 40ish than to just pick random traits as you go. It'll also give you something to work towards in-game. I don't think I saw a link to them anywhere aside from me (and others) showing builds. So here!
I personally prefer guildhead's but there's others out there... I only know of these 3, but if folks know of others let me know and I'll update the OP.
GW2Codex if you're looking for some ideas.
