Prediction Model

The Doorman Buff/Nerf Watch

This page is the hero-side version of the item prediction screen. The target is whether a hero looks more likely to be buffed, nerfed, or left alone in a future patch. This first page is The Doorman-only so the predictors can be reviewed before expanding to every hero.

Best read: this is now a three-stage experiment. It first asks whether The Doorman is likely to change, then which broad mechanic would be selected, then the direction of that selected mechanic. Later stages are conditional and must not be read as standalone certainty.

Stage 1: Will The Doorman receive any balance change in the next patch?
Stage 2: If The Doorman changes, which mechanic family is most likely to be selected?
Stage 3: If that family is selected, does its patch direction look like buff, nerf, or mixed/rework?
Future learning: Weekly snapshots preserve hero stats and ability values over time. They are enabled as model features only after changed and unchanged patches both have adequate coverage.

Three-Stage Next-Patch Forecast

Will The Doorman change?

18.2%

Estimated chance of any The Doorman balance change. No-change estimate: 81.8%.

Disclaimer: Experimental. This is based on one hero's patch history and has not been proven accurate — Stage 1 and Stage 2 don't yet beat a simple "no change" guess on holdout data. Treat every number on this page as a rough signal, not a confirmed forecast.

Stages 2 and 3: target and direction if The Doorman changes

Mechanic	Selected if changed	Direction	Buff if selected	Nerf if selected	Mixed/rework if selected	Combined priority
Doorway	12.8%	Mixed Or Rework	0.0%	37.5%	62.5%	2.3%
Luggage Cart	9.9%	Mixed Or Rework	0.0%	32.4%	67.6%	1.8%
Call Bell	9.7%	Nerf	0.0%	56.9%	43.1%	1.8%
Hotel Guest	4.5%	Mixed Or Rework	0.0%	24.9%	75.1%	0.8%
Vitality	1.5%	Mixed Or Rework	0.0%	20.8%	79.2%	0.3%
Weapon	1.3%	Mixed Or Rework	0.0%	14.7%	85.3%	0.2%
Spirit	1.2%	Mixed Or Rework	0.0%	13.2%	86.8%	0.2%

Combined priority multiplies Stage 1 by Stage 2 to help sort the watchlist. It is not a calibrated probability that the named mechanic will change.

Validation and Data Readiness

Every stage uses older patches for training and newer patches for testing. The current patch calendar contains 138 update dates through 2026-06-12.

Stage	Test rows	Balanced accuracy	Macro F1
Stage 1 - hero changedWhether The Doorman receives any balance change.	28	50.0%	0.462
Stage 2 - mechanic selectedWhich mechanic family is selected if The Doorman changes.	196	50.0%	0.487
Stage 3 - conditional directionBuff, nerf, or mixed/rework after a mechanic is selected.	1	0.0%	0.000

Performance feature gate: withheld. Historical pre-patch win-rate coverage is 0.0%; the required coverage is 80.0%. Performance features are withheld because missingness is too sparse or too strongly associated with whether The Doorman changed.

The weekly collector now stores all hero performance, base stats, and ability properties without overwriting prior snapshots. Once enough unchanged and changed patches have comparable coverage, performance and ability-strength features can enter training without leaking the answer.
