exotic saw

anyone ever counted if its worth it to upgrade exotic saw mils?

for 2 lvl 1s vs 1 lvl 2 difference on buffing takes 225 days to make back ur gold, but frees up a license

but in terms of straight production, 96 days.

I upgraded all mine. all i have is time and faster production is worth more to me than granite i can buy in trade tab anytime.
i look at it as one less thing to worry about, when it comes to advanced leveling you need all you can get on ex planks

Totally agree with Ausslite. Time is the power in this game. The more patience you have the greater the reward.
