All tests were done with maximum upgrades on all sides.
Me and a friend run several tests on the unit test map before the patch. As soon as the patch got live we repeated the same tests with the new stats. We did each test 4 times and microed each side two times. We avoided using terrain or using the carrier leach range, instead we wanted to check the results in a straight up battle. All tests are done with maximum upgrades for both sides.
We also did not include storm, disruptors, archons etc in order to not make the result harder to interpret. We just wanted to know if pure Carrier got easier to counter after the patch.
We are both Dimond players so our micro is very basic, but you can still see the difference between pre and post patch Carriers.
1 Carrier vs 3 Vikings
Even, sometimes the Carrier wins with a few hit points, sometimes a lone Viking with a few hit points.
The Carrier wins with about 24 hit points left.
1 Carrier vs 1 Thor
Pre patch: Thor win with 112 hit points
Post patch: Thor win with 101 hit points.
1 Carrier vs 2 Cyclone
Pre: Carrier with 120 hitpoints
Post: One cyclone with 88 hitpoints.
1 Carrier vs 1 BC
Pre: BC with 438 hitpoints.
Post: BC with 341 hitpoints.
10 Carriers vs 10 Liberator and 10 Vikings, trying to kill the interceptors first:
Pre: All Carriers left, all terran units dead
Post: Almost all Carriers left, all terran units dead
10 Carriers vs 20 Liberators, trying to kill the interceptors first
Pre: 2 Carriers left
Post: 10 Liberators left
10 Carriers (and 2 observers) vs 15 widow mines, 5 Thors
Pre: 4 Carriers
Post: Results varied a lot, between 4 Carriers left to 3 Thors left
10 Carriers vs 10 Thors, trying to kill the Carriers first:
Pre: 3 Thors left
Post 3.5 Thors left
10 Carriers vs 10 Thors, splash mode killing interceptors for half the battle, then single target mode
Pre: 4 Carriers left
Post: 6 Carriers left
Since cyclones did well against carrier in low number, we decided to test 10 Carriers vs 20 cyclones. We used the rapid-fire trick to make sure all Cyclones were firing.
We did not have any pre-data for this.
Post: 4 Carriers left
Carrier are stronger vs vikings, thors and bc in low number compared to pre patch.
Carriers in high number still beat viking/liberators.
Liberators in very high number do beat Carriers. The problem here is that 1-2 storms would make the Carriers win by a large margin.
Thors do ok vs Carriers in high number if Carriers do not abuse terrain or leach mode. Thors should always use the single target mode when fighting Carriers.
We expected widow mines to do better post patch since interceptors take more time to rebuild but for some reason widow mines were not as effective as we imagined. Results when widow mines were used also varied very much.
Cyclones while good vs low number of Carriers are not good vs Carriers in higher number.
Overall the Carrier change was a disappointment. We had hoped that Carriers would be easier to counter but the only working counters have very strong weaknesses. Thors work if terrain is good, no disruptors are present, and Carrier are not using leach range. BC work except the new Tempest are very good against BCs. Liberators work but you need very high number of liberators, making them very vulnerable to splash damage.
