What is the most self-sufficient single Job/Subjob combination (all gameplay)?

For a higher number of jobs that is certainly true. But I still feel like I can focus on WAR and THF simultaneously without sacrificing one for the other. Sure, one job will have a relic sooner than the other, but to me that's an arbitrary decision, I basically flipped a coin.

Well for WAR you need rag+Ukon to DD, and THF needs mandau, that's like 3 relic worth of weapon for just 2 jobs(you mentioned 3 jobs) And not counting some gil sink items like HQ abj augment. Again, maybe you're hardcore and able to afford everything, but for majority of players building 3 relics+ some HQ augment takes at least 10+ months. By that time more gear already come out. Majority of player I've met in this game pretty much focus on only 1 job(myself included, cuz I can never have enough time to work on so many gil sink items for more than 1 job), some focus on 2(usually if they have 2 characters, so 1 main job on 1 character), but focusing on 3 is pretty rare for sure.
