Hello,I always had that question in my mind,why Vana run is so profitable comparing with the other missions or the Arcade 3?They offer you very few crowns or crystals.
Ok I know,no one forces you to play Vana if you are got tired of it but I really do not get why things are like that.
The other stages are so pretty,and all the spiral concept wasnt that?To be in an enviroment that changes constantly,in one stage you might need this gear and in the other that gear.This make things less tiring,the opposite in fact it makes it intersting,it gives a purpose to buy and craft new weapons..
When I got bored I say I will just do an arcade run,but when I see the loots even with arena they are dissapointing.For players who are in the endgame and we got tired the endless vana farming we want 2 things.Not to play vana again and again and second to earn some crowns to expand our gear,even if the earnings were a bit less than vana,I guess many old players would prefer to play arcade..
You're right that FSC is very profitable. And you're right that this game is not well balanced in its payouts (or armor, or ...). But I think that you're overlooking some other opportunities.
Operation Crimson Hammer is similar in payout to FSC. By vendoring Perfect Mask of Seerus, you get an extra 30,000 crowns every three runs. (I'm assuming that you have extra Eternal Orbs lying around. Many end-game knights do.)
If you compute crowns per level, then the four danger missions pay less than FSC, but not much less --- 2,000 vs. 2,500, say. (See the data set here.)
Radiant Fire Crystals are more important than crowns for many end-game knights. FSC gives you about 15 of them. (See the data set here.) An Arcade run with deep arenas can give you more than that.
