While they are laughing it off, probably because it's 'reverse' i find it weird that it's a recurring theme in manga that you are obligated to rank up if you are strong.
Like, if I just want to make a living and can mill through orcs, why should I be obligated to go on dragon slaying expeditions.
Especially when the dragons are minding their own business but that's a different matter.
That said I always appreciate it when they don't arbitrarily promote strong people.
Not only does that potentially fill the ranks with problematic people if that's the only criteria but also the fact Guild is a business and if a strong adventurer only does one quest a month, why give them a ton of benefits as we often see instead of the person who does at least 6 quests a week and brings in steady revenue.
