Placement points and why the climb feels different
TFT pays out on placement across eight players rather than on a win in a two-team match. A second place is a good game, a fifth is a small loss, and a first every few lobbies does not make up for repeated bottom finishes. That maths is why Teamfight Tactics boosting orders here are quoted on tiers rather than on a number of wins.
The habit that moves a ladder is consistency: playing the strongest board available rather than forcing a comp, and knowing when a lobby is contested. Those are teachable, which is where a session earns its price. A Teamfight Tactics coaching block spent on economy timings and pivot points changes the average placement, and the average is what the ladder measures.
