I believe someone figured out that the best the LV can get is 6 for the armor resistance band. You can play it now, but I understand if you want it to be fully complete. In essence only scenarios are missing for the game as far as features are concerned, otherwise it's just polish and tightening up what exists currently. Understand that Kerberos will be doing that for the life of the franchise. SotS 1 is still slated for one more major "update", and it's been in existence for 6+ years. So I'm pretty confident that SotS 2 will get at least the same treatment.
