The patch 1.3.0 PTR is once again available for testing. With the help of player feedback, we've addressed several bugs with this update and made the following changes to unit balance:
The buff to Infestor health has been reverted.
Fungal Growth is now once again instant cast and will no longer fire a missile.
Ghost EMP now drains up to 100 energy instead of all available energy. The effect on Protoss shields remains unchanged.
While we're not currently anticipating any further changes in this PTR cycle and are very close to finalizing and releasing patch 1.3.0, we still encourage to you to hop onto the PTR client and continue testing. Check out the PTR FAQ to learn how:

We'd also like to thank everyone who's participated in the PTR thus far. Your reports and feedback have been very much appreciated!
