To be fair, if Kalmarunionen is afk by not attacking, then Astralis and HCE are also afk. They don't have the manpower to recruit tickets like HCE does so they will probably just take longer to get more stuff. Also the odds of Astralis or HCE attacking are unlikely and everyone else is focused elsewhere, the north is probably the most secure region right now.
disclaimer: Kalmars probably just dead though.
