Darkfall, skill selection was a wide-open field. When the game relaunched as Darkfall Unholy Wars, the role system was introduced, narrowing the field of options significantly. Now custom roles are incoming, and that means that players have questions about how the new mechanics will work. Those questions are being answered in a three-part series of community Q&A sessions, with the first two parts available now.
Some mechanics are being removed -- Wobble, for instance, was introduced solely to balance roles, but with the new system the developers no longer need balancing specifically between roles. There have been significant adjustments made to some skills, in part to avoid the situation wherein everyone has a ranged kill skill and super-powerful healing. Despite this, the answers also point out that most characters will actually see a net increase in power overall.
