The most notable and worthwhile change in my opinion is probably the Immortal Buff. That needed to happen a year ago.
Unit vision up ramps has been reduced by 1.
Attack range increased from 5 to 6.
Acceleration increased from 0.3 to 1.375.
The Mothership’s Cloaking Field no longer cloaks all units instantaneously, but rather adds units to the cloak field over time (maximum of 25 per second). This should alleviate “Mothership Lag” issue when a Mothership comes online.
Blink research time increased from 110 to 140.
Shields increased from 40 to 100.
Build time increased from 60 to 65.
Infernal Pre-Igniter damage upgrade decreased from 10 to 5.
Seeker missile movement speed increased from 2.5 to 2.953.
Fungal Growth damage changed from 36 (+30% armored) to 30 (40 vs Armored).
Morph cost decreased from 50/100 to 50/50.
Contaminate energy cost increased from 75 to 125.
Build time decreased from 70 to 55.
