Trailblazer, twisted, shattered. Trailblazer was the refined, younger brother of twisted, which polished the unrefined areas and gave new opportunities.

Shattered mainly suffered from diseconomy of scale, too many choices. Committing to a path in trailblazer defined your build. An interesting play would be to have a final relic where you can adopt a relic from other non chosen paths, much like pathfinder in path of exile
