Game updates
Click on the august 8th page, and scroll to the bottom, they added what they changed there. i believe they only make a new actual update page when they put out a decent sized update.
The pvp community reminds me of what Obi-kittenenobi describes Mos Eisley as from star wars.
“Updated to prepare for the September 7 Path of Fire stress test.”
