imo at the point you understand the flow of 6’s and what your role is in most situations, the game is largely mechanics. I find watching demos (of myself and people who’ve reached out to me), a lot of scenarios are like “well that play works fine if you hit those shots” or “you couldve surfed to make more out of your health there”, something to that effect. Maybe I’m biased bcus I’m a roamer player usually helping soldiers but ye once you have the gist of what a smart 6’s player wants to do and why, it comes down to things you can’t help 1 on 1 with a mentor (like coordination, comms, mechanics, etc)
that being said idk what level you’re at or what your understanding of 6s is like, my recommendation tho would be watching stvs of scrims/matches of ppl above your div. Maybe not top invite too because some of what you’ll see just isn’t the same as your div, but still is a good way to learn common positions, ideal pushes for certain scenarios, that sorta thing
