Didn't other people say that Suffixes increase your profit? Or are you thinking of something other than second mods?
I don't know what they said. I draw this conclusion from selling/buying two of the same weapon type, one with grinding, one with grinding and a suffix. The only-grinding one gave more profit.
But I think I can explain why. For example:
Weapon A costs 6 gold.
Weapon A sells for 3 gold.
Grinding Weapon A costs 9 gold.
Grinding Weapon A sells for 12 gold.
(These seem reasonable so far, no?)
Lets say we have a suffix that costs the same amount as the weapon alone.
Weapon A -suffix costs 12 gold.
Weapon A -suffix sells for 6 gold.
Now just add.
Grinding Weapon A -suffix costs 15 gold
Grinding Weapon A -suffix sells for 15 gold
Zero profit.
Or I can explain another way.
Lets say we have a weapon with 100 mods on it (this is an extreme, obviously). If we could sell for more than 35k, this weapon would probably sell for 200k. What do you think it would cost to buy it back? Probably 1Mill+. Add a Grinding prefix. Do you think that the Grinding prefix would be able to make up for that 800k+ and then some to give a profit? No. The point? If there is a suffix attached to a grinding weapon, that's more cost that Grinding has to make up for to give you the same profit. Remember, with anything other than Grinding (or Fool's) you can't make a profit; you lose money.
Speculation: I wonder what kind of profit you could get from a rare weapon with Grinding and Fool's. I also wonder how hard it would be to find such an item (normal, only those two prefixes).
