Yup, that's definitely what "skill crafting" implies. But I never really expected that sort of system. Theoretically moddable, though it would be a good amount of work to make it worthy of the name "skill crafting." Not super difficult per se, just tons of work making variants of different skills, new crafting recipes, balancing and making new skill effects and icons stuff.
Tyranny Devs managed to implement skill crafting and I anticipated that it will be much better in DOS2 due to more interesting "base skills" that are already present.
Besides, I am quite sceptical about 24 Source skills as they are not meant to be used often. I wish we could have other 24 ordinary skills instead.
My main concern here is about magic/physical damage dualism.
For example, if all the 4 Warfare hybrid skills deal physical damage, the system will not give new opportunities of dealing magic damage by warriors. If they deal magic damage, 4 skills are only a reasonable minimum (take into account ability points to spend too) while "physical" warriors will get nothing from skill crafting.
