Greetings to the Insane-WoW Community.
Recently I've decided to work on a few professions and I have seen that It's almost useless for learning one.
Because they are not balanced with our stats and level,for example JEWELCRAFTING.
You may learn a JEWELCRAFTING profession for sure,but the sockets are not updated and balanced for our stats and level(255).
Few socket's for example:
Brilliant Lionseye - giving +10 intellect instead of atleast 900-1000
Solid Empyrean Sapphire - giving +15 stamina instead of atleast 3000-4000
Bold Crimson Spinel - giving +10 strenght instead of atleast 2500-3500
Bright Crimson Spinel - giving +20 attack power insead of atleast 6000
Delicate Crimson Spinel - giving +10 agility instead of atleast 1500-2500
Runed Crimson Spinel - giving +12 spell damage instead of 1200-1700
Those stats are just an example for the Idea of main,you may balance them for the level and the stats.
