why are some players

able to flex easily and understand basic util usage on multiple agents then theres some players who struggle on literally a single agent?

its simple
they are just better

How players spend their play time would be a factor I think

Some players would rather spend time to hone many agents while others try and maximise every small bit of performance on their comfort agent

I was an RTS player back then and it helped my mega brain to adapt

I think some players do not feel confident in changing their playstyle around agents and the better ones tune themselves to the agent

"just flex bro"
