Question on a progression lockout

[Dreggit]

The best gear at 51 is either the archaeoskin set at I lvl 65 or the artisan's set at i60. Either way you'll need to meld in order to get where you need to be.you are also missing cross class skills since you don't have any other leveled crafters

I was told not to level other crafts or worry about cross class abilities because they were being removed. According to people in my FC of which has been less than helpful in crafting
