I kinda wanted to name that suggestion "balance crowns reward". But I'm sure this sub-section is littered with those. So no, I won't talk about Candlestick or Treasure Vault pitiful crowns rewards (ooops).

Instead, I'm going to state the obvious problem : endgame players, like me, farm FSC every day, all the time, simply because it's the most profitable level. That leads to a lack of diversity, obviously, which makes it very boring very fast. That's sad, because we already have a lot of interesting content the devs spend hours and hours and lots of sweat and pizzas and coffee to create, which is runned very little by greedy knights.

The goal is of my suggestions is to make most end-game content about as profitable as FSC without adding any new content or significant change.

First, let's look at OCH. It's known to have a very little crown reward, but there is that mat you get at the end. Much like Almirian Seals you get by killing Vanaduke, just allowing us to quickly cash out the Perfect Seerus Mask Fragment would make the mission profitable overnight! Either by directly cashing it out or adding it to Brinks to have a useful reward to it (more on that later).

Then, there are Shadow Lairs. When you look hard at it, the split cost of the key is about the same price as a 5* recipe. Which means that the entry cost of Shadow Lairs really pays for the mat. What if there was another version of Shadow Lairs that, instead of giving a crafting mat at the end, gave one of those mats used for Guild Hall Statues ?

That would make 2 main changes to the current system : those mats price would drop a lot, especially those from Vanaduke. Not sure that's a good thing, but there is always another solution (more on that later). The other would be that veteran knights, those who seek out Statues, wouldn't have to venture into boring T1 and T2 boss runs. And at the same time, yes, we now have 4 more profitable levels to diversify the daily grind!

You may ask : hey, what's the point for OOO ? Apart from diversifying the daily grind, which is already a plus since it may keep players for a longer time (after all, you need stuff to do those shadow lairs, and if it's less boring, people may stay longer), the big thing is it could be a DLC, like OCH (hell, even 1 DLC per shadow lair if they want to). I bet I'm not the only one who would be happy to have a one-off fee to run Shadow Lair as many times as I want.

Sum up of all that :
- make a Brinks reward for OCH mat so we can cash it out (for about the same profit as FSC overall)
- make a new DLC version of Shadow Lair, which doesn't require a key, but doesn't give the SL mat, and instead give a Statue mat

But wait, there is more! I talked about "more on that later" two times. What if instead of the statue mat in SL and cash reward for Seerus mat, we could have another "guild furniture" token ? That's obviously something which doesn't exist. It would be simply, a new token that you can use only to buy guild furnitures. It can replace crowns, at for example 1 token = 1K crowns change (or simply add 1K crowns when you transfer it to treasury). That would obviously, on one hand, reduce the crown sink that guild hall is. On the other hand, that would incentivize players to invest in the guild hall, this investing more of their profit in it, and at the same time reduce default rates (since every player would have some token that they can't use for anything else).

And adding that new token would have the advantage of letting developers tailor it to their liking, contrary to existing tokens/amts which already have known costs which could be hard to adjusts.

Any obvious flaw on my reasonings ?
