how to choose your role?

this is more for pros but im having trouble chosing what role i want to play.

cant decide between;

recon - fade sova
smoker -
flasher - kayo skye etc
sentinel

how did you decide your role?

Smoker - cypher cage, no cap

smoker- jett

ez advice if you prefer explosive get in the face playstyle go for duelist/initiator
and if you like supporting/lurking/clutch scenarios go for sentinel/smoke

flasher - Yoru

i like to play agents with cool looks
Chamber, Sova and Omen

I instalock chamber and taps head and win the game ez
