Well... I thought builder could be one of the jobs, like cleaner. You can either use your own crew or hire one. For now, you're right, I'll just leave the cost and time it takes to build an upgrade.
I am going to recode jobs as well, current system is awkward, boring and difficult to manage.
PS: You can slowly start working on basetraits and mobs, system might have to be expanded but we need new traits for jobs to work properly and mobs to be interesting. We also (imo) should rename all spells back to FF standards and full names for unique once. Current way of naming is very confusing. There are also a couple images missing and one of the sound files...
+ A lot of sounds are off.
*Maybe we should just stick with three - four spells per element for now... and comment out the rest.
