Is production class better than farming mats and selling?

I wanted to know is it beneficial to have a production chr like refiner/statter/alchemist.?
Is it better than selling anti degradation?
How oftenly will I get coustmer if I go refiner or started?
And how much profit could I make?

Thanks for the help.

 

depend on demand
cz not all ppl always refine and stat their equipment
example when new equipment release out maybe many ppl need stater or refiner
selling anti degradation also worth to sell for increase your spina

 

you should pick what you need the most for yourself, then try to sell it to others

 

If you want to be refiner, you NEED TO GAIN TRUST first.
And it will be boring if you only do one job.XD
Go farmer/refiner/stater/ache/seller.XD

 

i want a refiner for myself and my guild. My refiner is also alche. I plan on making it stater too.
Still I want to know how much profit can I make subtracting all the investment like money spent on ores etc.
