It was only a joke. Things are not as serious as I said above.
wow that's all pretty negative
edit: why am i complaining about that
wait because it's not really good feedback? go into more detail
I was just joking. I like these races.
But there are really some concerns. I understand that for a mod to be popular, it's good to have more stuff to play but less frustrating than vanilla. Just something went too far. Priest magically get iron from thin air, a single gem emits unlimited magma. If something is going to be overwhelming, it should be week in the beginning, at least it shouldn't be overwhelming from the beginning. So trap upgrading is perfect, volcanic plate armor is fine, golem is a good flavor, but javelin looks like only a name for a cheating crossbow.
Human mode need not to be balanced against other races, more challenge is fun. But it can be more fun if human has some unique stuff. When I'm playing as human I just build and work until one day I suddenly realize that I've made enough wealth to buy all things I want to buy, and I will never get the other things. It's a good tour to MDF races, but human itself is not a race for seriously playing. Maybe builders will like it, but I'm not a builder, even in Minecraft.
Machines are interesting, but the fun part is to design and build them. Once built, they are useless. Build a smelting system but find that there are not many ores to smelt. Build a decorating machine but don't want to waste high-value materials in this unskilled autoworker. Build a deadly mechanical trap but have no way to lure goblins to siege. It's still fun to design machines, but it'll be better to design machines for some practical goal.
