How cumulative tiers work
Bronze establishes an ability's base behavior. Silver keeps that behavior and adds a second layer, while Gold keeps both earlier layers and adds a third. That means tier comparisons need to examine the complete stack, not just a larger icon or rating.
The official article explains the model through examples, but it does not publish the full catalog, all tier effects, exact tuning numbers, or every mode in which each ability can appear.
Enforcer and Lurker examples
EA describes Enforcer Bronze as improving hit-stick success, Silver as adding a larger timing-forgiveness window, and Gold as adding a fumble bonus. These are distinct layers, not three copies of the same effect.
For Lurker, Bronze adds jumping interceptions and diving swats, Silver adds reactions to tipped balls, and Gold adds ball security plus unlimited stamina after an interception. The examples demonstrate the tier logic without establishing a universal ranking.
Hot and Cold states
EA says positive plays can move a player toward Hot while negative events can move that player toward Cold. A Hot state is required for X-Factor activation; a Cold state disables the X-Factor until momentum is restored.
The cited material does not provide a complete event-by-event trigger table, duration formula, reset rule, or numeric attribute change for every state. Those details remain build-sensitive.
Compare abilities without inventing a tier list
Start with role and situation: identify the action the player performs, then compare which tier layers support it. An additional effect can be valuable without making that ability best for every position, archetype, or mode.
Before treating a build recommendation as reliable, record the exact player item or roster player, mode, ability tier, activation state, opponent, platform, and title update. A menu description alone does not establish in-game value.
