Previously Classic was listing Spar + CTF & Battlegrounds statistics within profiles. This would have been somewhat problematic and inefficient in the process of adding more events or stat types in future.
Now there is a separate GUI to view these, you can access your own stats through the bottom right options button. To access another player's stats, you can right click them on the playerlist, where there's a new entry named "Statistics". Unfortunately this does not work for the external V5 playerlist.
For the sake of accessing stats without logging into the game, these are also stored offline as text files within Graal/Scriptfiles/Classic/.
Once a certain NPC-Server bug is fixed, it will be made possible to open this window for players on other servers, RCs, aswell as a text box within Options to view offline player stats.
