So what skills can we expect at lvl 60?

I predict we will get one new skill, and it will not be cross-class but the same skill across all classes: Advanced Synthesis. 200% synthesis rate, 28 CP cost, 90% success rate. So, in other words, a meh skill that is situationally useful at best.

Remember, we're only going up ten levels, and cross-class skills only crop up every 13 or 22 levels. A 10 level increase seems like it's too soon to expect any new cross-class abilities.

As has been noted, though, gaining two new cross-class ability slots will make it worthwhile regardless of what new skills we get!

I'd like to see them go away from the current structure of leveling every class to 50 and cross classing the optimum rotation, effectively making all 8 crafting classes play identically to one another.

Maybe a job system that only lets you cross class with certain crafts, or limit cross class skill number. They'd need to revamp the recipes to not be absurd like they currently are.
