I'm going to throw my 2 cents in for ya to give you an idea of what I think some people are trying to say with the term "alternate builds" or "better builds".
Key Focus "AA"
Arcane Archer does not have to be a ranger. Example is the Elf race, if you go elf, at level 20 you can go AA. True it sucks while leveling, but the benifits for high end game playing outway the leveling time. As you stated you wanted a final build.
If you go fighter levels (atleast 12) you can get all of the bonus feats to put in as you choose to boost your ranged damage (more than likely having enough left over to boost the second weapon set aswell) and still able to take the 6 levels of ranger that give you most of the important feats rangers get given to them. You can also get more AC out of it and HP's to help tide you over while your slinging them arrows. Evasion is still easy enough to get with 2 levels of monk/rogue giving there class bonuses with it IE wisdomAC and or trap skills.
There are hundreds of ways to better your toons with what is presented in DDO and the most important thing is not to take what people here say as FACT. In the end it is your toon and should be allowed to play it the way you want to. That said, not all basic, general, or proven builds are the best and what works for me, may not work for your play style. All advice I give is from my perspective/experience and reflects nothing on you as a player. Hope what I said was news regarding AA fighters and what not. Enjoy the game.
