I know that it would take quite some database space to implement this:
But is it possible to enable comments on builds?
Someone could make the best, or the worst possible build. and nobody would know. as not many people use the "Thumbs up" feature.
Adding a comments section for each build would allow users to discuss the builds, and also point out flaws. this in turn will improve the quality of the builds that are posted.
Also this site promotes raw dps over anything else in weapons.
I know that it would be hard to calculate the effects weapons, or certain mods do. but right now the "top builds" are often terrible in the game itself, simply because they have high raw dps, but nothing else to them. adding a comments section to each build, would help filter those builds out.
