I actually wouldn't mind new jobs starting at lower levels, and not just have the entire level 80 kit dumped on me all at once. Let me get used to a simpler set of skills first, and watch the job grow and mature across the leveling journey.

People are complaining they run out of content too quickly and there's nothing to do, and although "level grind" may not be exactly what people have in mind I don't see how it's dramatically worse than no-life grinding FATEs all day in a Bozja-like zone. At least you have your pick of ways to level -- FATEs, dungeons, tribal dailies, roulettes, Deep Dungeon, get a boost from Wondrous Tails turn-ins. Or literally go no-life a Bozja-like zone again if you want.

Heck, maybe they could think about giving us a third new job for the 7.5 patch and have it start at level 1? I think I'd take that over a criterion dungeon.
