Ive watched ban from when he was t2 in NA and when he used to stream in NA, and honestly I think t1 just need to put him on jett or chamber, or just a duelist. You can tell that he isnt the most comfortable on controller and when t1 plays fracture ban actually seems alot better on jett. I know it may seem insane to put saya on a different role because hes been fragging out as main duelist, but saya could easily just play as secondary duelist, or maybe even go to controller like when he went by spyder.
