3 max stones in 10 hours means in a couple of weeks you'll have full +15, and never have to farm for it again. Like I said, it's meant to be a slow progression that gives you something to build toward for a long time.
Couple of weeks? Hmmm
3 stones = 10 hours of farming. Let's see how that holds up.
You need 75 stones for 1 set of armor/weapons full +15. 75/3 = 25. Going to have to get 3 stones 25 times. So you'll have to do 10 hours of farming 25 times. 250 hours
But wait, you got your craft set but you still need a e def/phys def set depending on what class you are. That's another 45 stones you need. Add on 150 hours of farming.
Well now you have your foc gloves but what about the people that would use either crit rate or crit % gloves? What about atk speed? That's about 30 stones for the 2 gloves right there. +100 hours of farming.
So that's around 500 hours of farming going off your 3 stones in 10 hours. Even if you farmed 10 hours a day every single day it's going to take 50 days to get full +15. Good luck gearing an alt.
Even if you cut out all of the extra stuff (shouldn't be called fully geared if you don't have) and only go with the original set that's still 250 hours of farming. Who is going to farm 10 hours a day 25 days straight to gear up? I remember being told that this was a casual game. What's casual about that?
