Does it mean encounters are RT until someone shoots?
no, thats how TB encounters works.. it works like this :
RT only :
- your forced encounters are RT
- you can find /be forced into player's encounters which are in RT
TB only :
- your forced encounters are in TB
- you can find /be forced into player's encounters which are in TB
both modes :
- your forced encounters are in RT
- you can find /be forced into player's encounters which are in RT or TB
