CBK
One thing that is also needed to be minded of is that there's a lot of the people are killing each other's alts as a way of getting CBK kills, Every time I come to takumi I see lots of people afk at the entrance to takumi waiting for bi to pass so they can kill their alts or what not.
The problem here is obviously that Rogues do can kill each other and get the same benfits as killing an enemy villager,
and since they're both rogue there is no real worry about running all the way back to takumi, and they get to repeat it very easily.
(A lot of the rogues get this mission, and so there is always a constant need for kills and so they help each other out.)
Maybe 140 is not the correct amount, but 500 is ridiculous. but for sure no daily mission (imo) deserves such a high reward, we need to remember that this is not a one time mission, it's a daily mission.
If you really want to increase it I'd go for 240 MAX, nothing beyond that point. Guard duty
(Guard Duty Is a mission where you are supposed to be guarding your village entrance for 30 minutes,
We need to remember that there's a difference between what the mission is, and what is done in practice,
The thing with Guard duty is that there is a problem with making the players actually guard, The only things
that reinforce players to keep an eye out and to be guarding is that fainting resets your time and you have to
guard 30 more mins but Guard duty maps are SF so most people don't go there to get kills or anything so a
threat is very unlikely, Second is Enemies who are surveying, which Interrupts them by very little time, so it's
not worth to even bother.)
So Guarding you Village for 30 minutes indeed worthy of having 300 ryo reward.
(If you want to fix it so people wont afk at GD than we need to make either more missions that threat the people who are guarding at GD maps or make GD maps a danger zone [I am not really thinking that's what should implemented but yeah that would defiantly encourage more people to Keep an eye when guarding the village.] )
{But than people will see GD mission as too harsh or not worth the time if it becomes so, and they'll rather abandon it, my suggestion is just make Guarding the Village less time}. If you managed to read all of this You get a virtual cookie from me to you.
