Traits were rebalanced, except for classes, I'll push them later. There were some incorrect fields, like old refinement stat or bonus to max upkeep, I fixed them too.
Anyway, I need to know for sure which stats will be useful for specific jobs (skills aside, of course). Classes are too powerful. They should be based on info from your code, not just my imagination.
Also we cannot remove mod field completely right now since it modifies upkeep. One of the options is to replace it with another field exclusively for upkeep.
