I think there IS a problem actually with Leveling. The bottom portion of the reward is the additional bonus you get for being the 'Adventurer in Need (Class)' this portion, is not being applied correctly every the time. For example, Yesterday (10/01/2016) when doing the Leveling roulette I received the 'Adventurer in Need (Class)' bonus but not the base, however I was not the needed class. Today, however it worked properly, the only notable difference is we had a first-time completion bonus, compared to the previous day. Both times it was Bowl of Embers (Ifrit), both time it was Tank in need while also both times I healed.

While my sample size is small, it does show a problem with how its being calculated. -- A thought occurs to me, the Guildhests roulette bonus is 50% on seals, while the Leveling bonus is 400%, not sure if that is a mistake or what...
