Ishgard restoration is planned for 5.1 or later which means it wont arrive before October. But leveling is pretty easy with Miqo.
1. Go to ffxivcrafting website: https://ffxivcrafting.com/crafting
2. Select job and levels 1-10.
3. Click Synthesize.
4. Use my scenario generator: https://miqobot.com/forum/forums/topic/crafting-scenario-generator/
Then buy raw mats from NPC and watch Miqo fill your crafting log. Repeat for the next 10 levels until you hit 30 or so. Then choose a simple recipe with easy mats and grind it for as long as it seems reasonable. When you hit 50 start doing levequests and farm red scrips.
