The options to make a character and build it around weapon or guild skills should be as good as using class skills. I dont understand why you get shoe horned in to having to use class skills if it's not your interest.
It is extreamly easy to make a good Stam build without using class skills. Mag is a little more difficult, but still doable. On the other hand it is almost impossible for most of the classes to make a good build with just class skills.
