Firebathero: Terran-> Protoss
Chavi: Zerg -> Protoss
-Air Force Coach Song Dong Kyun states: First of all, FBH changed to Protoss. His skill is really good and he is very high level. You may expect much from him. Also, Great and Chavi changed their races in SCII.
Flash: Terran -> Terran
-KT Rolster coach Lee Ji Hoon states: Flash wanted to try Protoss but has not changed the race. It is too early to decide whether to change or not.
Leta: Terran -> Terran
Rush: Terran -> Zerg
-CJ Entus coach Kim Dong Woo states: Leta gave a try playing Protoss but returned playing Terran. Rush played Terran in BW but he is currently playing Zerg in SCII. We still have to wait until he actually plays in tournaments to see which race he chooses.
Jangbi: Protoss -> Protoss
-Samsung Khan coach January states: As "Jangbi" wanted to change to Terran, he has tried playing as Terran, but eventually could not give up on his original race Protoss. However, he still says Terran is better.
Light: Terran -> Terran
-Woongjin Stars coach Lee Jae Kyun states: Light tried playing Protoss for three days but kept his original race. I heard there is only one player in our team who is still trying to change the race.
-Light states: Even I think Zerg seems to be the weakest. If you play well enough, Terran seems to be just as good in BW but it is not really "good yet." It is much harder to adapt to Terran of SCII than BW.
-STX Soul coach Kim Eun Dong states: That is Calm
-Calm states: Before I began to play SCII, I have thought a lot about choosing races. Out of all the reasons to change, I think it would be fun to play as a different race. Also for the fan's perspective, I think they would feel refreshed to see the BW players to play as different races.
Team 8 Coach Han Sang-Yong states: No players in our team changed races. However, we are still keeping it into a consideration because the Zerg players are having a lot of trouble. ***** This has been stated from many players and coaches all over the BW teams that BW zerg players are having a hard time in SCII.
- Movie has changed his team to Team 8, and he also has started to play SCII recently.
SKT1 coach Park Yong Woon states: Our team has tried playing different races in SCII but since it was very hard to adapt I have asked to keep the original races. All of SKT1 players chose to play the same race as in BW.
Interesting interview question asked to Stork and Flash: When I asked the GSL players, they stated that if you were good in BW you will be good in SCII. But, to become "competitive" it takes about 6 months of practice at least. How long do you think it will take for you guys [Stork and Flash]?
-Stork: My skill in SCII is not up to par yet so I cannot say being good in BW means you will be good in SCII. I think what determines your skill is how well you adapt to SCII. We practice SCII mostly on the ladder but compared to existing GSL players, we are not good enough [they are much better].
-Flash states: I think it would take about three months of practice to become competitive in SCII scene. However, strictly speaking it would take at least an year. To become as good as I was in BW, it would take about 2-3 years.
