Not trolling on your topic, but I fail to understand how this post came about. I never heard, read anything that would suggest this ARC <job> BRD setup. Could you relay a cite?

But taking from the subject, It's completely incomprehensible how the two could relate. Though I have my theory that classes won't be bound to just a single job, ex. CON <job> BLM or WHM. THM would seem best for a BRD. But I haven't put a lot of thought into it.

Job speculation is the worst hobby to invest in FFXIV imo. Gives me a headache. Simply too little official information.
