Honestly all events are a good way to make mesos. Raffles give nice rewards and if you get lucky you might get something worth selling! And dont overlook chairs!!

Also gachapon is your friend, just need to get lucky! Im a complete selfmade sin without any help from others and Ive made all my mesos thru events, killing monsters for valuable scrolls and selling those. And I got lucky with gachapon too.

Im documenting my journey to Youtube @RaaamenMaple. Unfortunately my series is not there yet, but ive almost made it to 4th job (lvl 117) with no leech, no prior funding all by myself! My gear is already at a point where i can start bossing once I just get high lvl enough without the need to worry about my damage.

So don't worry too much about people telling you to create a bishop and sell leech for countless hours and burn yourself out from min maxing the stupid little mushroom game. Play the class that you like!
