Well, you do agree certain agents are better then others in different metas, right? Lets say a sudden certain meta change causes a need for a certain agent which is just too good in that meta. Let's say Kay/O. The flex player should play Kay/O, yes? What if they are not comfortable on it and they just dumb down to average all of a sudden? But they have to work around it because Kay/O is just too good to leave or others will have advantage over you. An other player on the roster plays Kay/O? What if there is no one on the whole team who is comfortable on Kay/O? An issue, no?
That's why I said technically and asked does and can a team like this exist which always works around it?
I mean you can say "fuck it, we think Kay/O is not working for us at all let's go back to our original comp". Boom, their comes an underdog team or even any other team which includes players perfect for the changed meta and start dominating out of a sudden even though they were doing average before.
That's also why we see new rosters come up in a new meta and die down in a different one if they are late to find their footing for example The Guard
Also, the DRX 6th man roster was a total flop but I do think it was not implemented in a good way by any means.
