I am far from a newbie tho I worked this way being fully aware of it, I was just trying to circumvent the ilv requirement of the initial story dungeons (ifrit, mog king, levi and ramuth).
In the end it worked out perfectly fine for me as a WHM and while I was farming tomes was just an incentive to chain run ifrit for me because the weapon wouldn't drop (and I dint read in to the relic yet at that point) plus I dint want to go into the post lv 50 the dungeon with a lv 42 weapon and seeing with the current gear I had at that point had no troubles with ifrit so I just committed myself in running that and the daily roulettes both of them (must admit I got very lucky) because the period I was chain running Ifrit there was a large influx of new players for some weird reason so I got lots of first time bonuses.
Btw I dint go accessories fist I went for the belt, and wrists. (besides the weapon these where the most awful parts I had) bought some cheap rings, earrings and neck of the ah.
Let just say in the second day after I hit 50 I bought both of them with some tomes to spare.
Besides the Artifact gear wasn't that bad for the initial story dungeons (used it till ramuh I think) at that point I was swimming in tomes that I bought the legs (already replaced neck and ring) worked my way up till Snowclock in the next couple of days hit the ilv restiction again but I was close, so The day after that I went daily roulettes, finished unlocking crystal tower went first part for the bonus and bought the chest piece. (already had the Ifrit wep but found out about the relic so I started working on that instead)
In the end I might have cost me a 1-2 evenings extra but It dint matter for seeing the story line took effectively up more of my game time then the gear restrictions. that and the distractions of Gold saucer,dailies, crafting etc I knew with my limited playtime I could take advantage of the daily roulette so they where the main source of tome income for me.
I might not have any issues with it because I rolled a healer so I could effectively run the random duties and it was the most effective way to spend my evenings. I definitely would not have done it this way with a DPS class with that I would have focused on the right side gear first.
So in the end I really think it depends on what role you roll and how you spend your available game time I guess
