No, the whole need for the Job system was to bring back the Final Fantasy Feel to Final Fantasy XIV. And I don't feel that implementing the Job System as a Ragnarök Specialization system would work for that. This has nothing to do with being a snowflake, It has everything to do with being able to do things that past final fantasy's let us do. With the locked down system you can't be a Great Axe Wielding Subverter if all of Thiefs Skills are only available to thief and thief can only be used on Pugilist. But in FFXI I could.
hell 90% of my favorite play styles would become unusable if the jobs were locked down. If thats the case why play the game at all? If jobs gave you skills you could then share amongst all your classes and jobs it wouldn't matter I could go snowflake and be what I wanted. But jobs give you access to specific skills no one else has access too and if thats the case, and weapons are locked to a 1 class 1 job bases it means tons of fun playstyles focused around specific jobs and skills from XI and other final fantasy's no longer become usable even if they are fun, usable, and not gimp.
