a bit confused by these roles, what I expected was
duelist: saya
initiator- xeta
controller- munchkin
sentinel- carpe
flashes/flex- ban
main consideration is to ease carpes workload. initiators require chemistry and good timings and constant use of utility in response to the other team. a sentinel would allow carpe to really just focus on his aim and positioning. not sure why he was on probabaly the most difficult role
