zekken has been spamming sova in ranked too.
I'm assuming roles between reduxx and zekken for each map will be
Icebox - Reduxx jett, Zekken sova
Sunset - Reduxx omen, Zekken neon or raze
Lotus - Reduxx omen, Zekken neon or raze (most likely raze)
Ascent - Reduxx yoru (he seems to be playing him on ascent in ranked) or jett (most likely jett), Zekken sova
Bind - Reduxx gekko, Zekken raze
Haven - Reduxx omen, Zekken neon
Abyss - Reduxx jett or yoru (most likely jett), Zekken sova
All of this information came from ranked, so it might be completely wrong.
