What you described is a wargame like Warhammer AoS/40K, not a role playing game.
What I described is literally what every tabletop RPG is...D&D, Pathfinder, etc...whatever your favorite is. If there are dice involved your main task is creating a character with the best chance to land its attacks and spells, and the best chance to negate damage coming your way. If it's a game of chance you are ALWAYS playing the odds...no matter how much or how little you think you are min-maxing, no matter how much you think should be optimized, the game forces you to play the odds and to optimize to some extent...the entire game is literally ALL about your odds. Every action is about your odds of success vs odds of failure.
You are literally not allowed to play until you created a character...and that entire process is optimization...what's your role in the party, what abilities do you take, how do you attack, what are your odds of success and how much damage do you do, etc. etc. etc.
