It feels really shitty when you don't hit Stage 4-5 when you're trying to win.

TFT has a mission that grants you points when you get to stage 4-6, which is not what's written in the client. It is by far the more time consuming mission related to this game mode. I get why the threshold is there: it's for players that really want to win and to prevent players from just afk-farming this mission. But it feels extremely shitty if you lose at any point in stage 4. You've wasted your time you've put in it, and to me I feel like it outweighs the fun of playing the game.

Please consider putting "altering this mission level" on your "To-Do" list. Or a"To-Don't" list. Any list will do at this point after several weeks of this mission.
