Even many of the so called cookie cutter builds today are honest about those talents that are a toss up. Picking talent A over talent B may be a theoretical dps benefit in the sims or even for the author of the cookie cutter build, but that doesn't mean it will work for you. I have deviated from these sacred builds often on my own characters because I found that I don't rely on certain abilities or mechanics as much as the build assumes I should. Now maybe my dps (healing, etc.) would improve if I could manage to do that, but in the interim using a build that is bad for me just because it's the anointed one doesn't make sense. A- dps with the "bad" build is superior to C+ dps with the "good" build.
