I've obtained data from their corresponding VCT Leagues to know which duelist is the most successful at opening the map. Here are the results:
- In EMEA: Derke (with 0.61 First Kill Success Rate and 0.42 Aggressiveness Rate)
- In Americas: aspas (0.6 FKSR) and dgzin (with 0.39 AR)
- In Pacific: something (0.61 FKSR) and Seoldam (with 0.44 AR)
