Included is the fix we have all been waiting for:
Monstrous Kaliri have learned how to chase players going straight up.
On the plus side:
With the 2.4.0 PTR, we will be allowing US, EU and Korean players to access all available PTR realms. Players will be able to choose which test realm they wish to play on without being restricted by region. We currently plan to make all PTR realms available in this way for all future patches.
The arenas are currently disabled to help focus the testing on Warsong Gulch. Hopefully they will start to roll out some Arena balancing changes after they get the PvE and BG testing out of the way.
