Being able to feel the progression and enjoy all of its content with my limited time. Game does not need try to be competitive to be fun and chellenging. Hindering players does not make this game balanced but more unaccesible. You can make Tarkov enjoyable for every kind of player, be it hardcore or casual, pvp or pve, not taking from either of them, just give them choice to play their way. Make the aspects of game more challenging but reward it, make others more chill but less rewarding and let new/casual players feel the progression and eventually those people will feel comfortable with more chellenging activities and pvp.
make it enjoyable for every player is impossible unfortunately
