Is there a plan on how the factions are released?
To me, it seems they are very aware of the popularity of TOW, now they already showed what is coming for chaos, and for the last few years at least (9th/10th edition in 40k), they have effective point balancing mechanisms in place. I would be surprised if they don’t make use of that after they have released all the planned factions. Maybe it won‘t solve all balancing issues, but at least with The Empire, I feel like some point adjustments would change a lot. Furthermore, it should be easy to make slight changes like 0-1 Greatswords per 1000p if you take a general etc. It only needs a pdf errata.
But all of that only really makes sense when everything is out there and the community has become familiar with all of the new mechanics and the potential of the system.
