HOTS NEW UPDATE
To accompany the deployment of Heart of the Swarm Beta patch 2.0.2, we’ve compiled a list of all of the balance changes made to the beta since our previous update.
 
Terran
 
Medivac
New ability: Emergency Thrusters
Speed boost that increases movement speed and acceleration to 4.25 for 8 seconds. 20 second cooldown.
The Medivac’s Caduceus Reactor upgrade at the Starport Tech Lab:
Health restored per second from 9 to 15.
Energy cost reduced from 3 health per 1 energy to 5 health per 1 energy.
Cost increased from 100/100 and 80 seconds to 150/150 and 110 seconds.
 
Reaper
Base speed increased from 2.95 to 3.375
Upgraded speed increased from 3.84 to 4.25.
 
Widow Mine
No longer hits cloaked units.
New upgrade: Drilling Claws
Decreases burrow time from 3 to 1 second.
Requires Tech Lab and Armory. Costs 150/150, 110 second research time.
 
Thor
250mm Strike Cannons has been removed.
The Thor can now switch between two modes: High-Impact Payload and Explosive Payload. The mode shift takes 4 seconds.
When in High-Impact Payload mode, the Thor switches to a different anti-air gun (250mm Punisher Cannons) that has 10 range and deals 24 flat damage.
Thor radius, inner radius, and separation radius increased from 0.8215 to 1.
 
Raven
Seeker Missile has been redesigned:
Can now fire from 10 range.
Missile comes out and stays immobile in front of the Raven for 3 seconds while charging up, then rapidly moves (it’s not dodgeable at this point) and explodes at the target for 300 single target damage.
Targeted unit lights up red when targeted. If the unit moves 13 range out of where the Seeker Missile is, the Missile fizzles.
 
Hellbat
Splash damage radius increased from 90 to 110.

The Armory now only has one weapon and one armor upgrade for both air and ground upgrades for both Factory and Starport units.
