Hard to tell tbh since we haven't seen the teams play these maps in a while. Based on form on pearl, SEN obviously look better, but I feel like it always happens where one team looks great map one and then can really struggle on the later maps and lose gunfights that they were winning before.
100th had a great haven in late 2024, but they haven't played it since then, Sen is also pretty weak at it since the beggining of the year. 100T should be favored going into it, but it's hard to know what to expect
