If anything, the most likely new feature in the next expansion is a new class.
- They need new features for selling expansions.
- It's easier to sell a new class than additional specs for existing classes.
- The worker resources previously spent on borrowed powers and additional systems is now used on actual class design (as seen in current expansion)
- They just added a spec with a new role, forcing them to add more specs with that role soon to make easier for them class balance and design.
