I played this game until week 13 and even though it's a great game there are some subjective problems with the current version / v.0.8.2 that i listed here:
First problem: farming money with the board is so overpowerd ,because when you have enough slaves, you can earn over 3000 gold in 2 days.
Second problem: the market sometimes sells so overpowerd stuff like full mythril gear for 400 gold, that you can do a hard dungeon already in week 3, which makes upgrading the forge for gear nearly useless.
Third problem: the guilds slaves are even with their quality upgraded 4 times terribly bad and sometimes even have 4 terrible staats.
Fourth problem: the classes all feel the same, there should be special weapons for every class (like a guitar for the bard) and special social and combat skills.
Fifth problem: there are too little trainning perks / the perks are too cheap even with the raise of the price for every other locked perk when you buy one.
Sixth problem: there are too little costumes, that give a certian bonus, there should be for example instead of the worker outfit others like a fisher outfit.
