flexibility is good because you can change stuff up and don't have to run the same thing over and over. take prx for example. their previous comp on lotus had cypher instead of breach. but because f0rsaken is a really good flex, he switched from sentinel to initiator and prx lotus has been insane since the change. or take tenz for example. not a conventional flex because he mainly plays omen, but he got off of yoru on bind to play gekko, and their bind has been better since. or victor for example. nrg been pretty mid recently, but in 2023, his ability to play both neon and raze in addition to kayo or killjoy helped nrg out a lot, given that ardiis could only play jett. additionally, having flexibility allows you to take other teams off guard with off-meta comps. also, I do want to point out: optic had victor, fnc had chronicle, so major winners do have flex players.
