Don't need the jobs unlocked to get their weapons, just need the minions.
And yeah, you got a couple months here Ralph, no need to rush super fast. I also find for the most part the tomestone gear you get at 50 should be sufficient enough until you get to 60 and get that tomestone gear, which in turn is sufficient until 70 and then the same until 80.
If you get the augmented stuff (which I think is all you can get now with the change they made in 5.3, no?), it doesn't get outclassed by dungeon gear until the level 55/65/75 dungeons. And even then, the ilvl increase is only a couple levels each dungeon after that. Just get the tomestone gear and upgrade where you can from dungeon drops. You get guaranteed drops from dungeons now so you'll definitely get a couple pieces from the level x5, x7 and x9 dungeons
