Currently ASTRAL doesnt support Queueing PvP (it for sure will in the future).. but if you want to bot right now you can combine the AFK PVP AutoHotKey Script + Astral.
Step 1. Join a couple matches and make paths for each map
Step 2. Modify the AHK Script to start/stop the bot when you join a match.
Step 3. Monitor bot, sometimes it gets stuck. Still better than manual labor
