Dr. R.O.T: Rotation Timeline

The timeline is the core of Dr. R.O.T. It shows every cast your selected player made during the fight, aligned against the top ranked players for that spec.

Spell Icons

Each cast is shown as the spell's WoW icon. Hover to see the spell name, timestamp, and whether it is a cooldown ability.

Heroism Windows

Golden highlighted regions show when Heroism/Bloodlust was active. Check if your cooldowns aligned with these windows.

Zoom and Pan

Scroll to zoom in on specific time ranges. Click and drag to pan the timeline. The minimap at the bottom shows your current viewport.

Region/Faction Filters

Filter the ranked players by region (US, EU, KR, TW) or faction (Alliance, Horde) to compare against players in your bracket.

Dr. R.O.T: Performance Summary

Below the timeline, the summary panel breaks down your performance into actionable categories:

Activity and Uptime How busy were you? Compares your casts-per-minute and downtime against top players.

Cooldown Alignment Did you use your major cooldowns during Heroism? Shows which CDs you missed.

Cooldown Efficiency How many times you could have used each CD vs. how many times you did. Missed uses are highlighted. Engineering consumables like Sapper Charges are tracked separately in the consumables section.

Cast Distribution Spell priority comparison. Shows the biggest differences between your cast mix and the top players.

Opening Sequence Side-by-side comparison of your first 8 casts vs. the top players' openers.

Potion and Sapper Usage Pre-pot detection, combat pot timing, overall potion efficiency, and engineering sapper charge tracking.

Buff and Debuff Uptimes Tracks your key buff/debuff uptimes and flags when they drop below target. Correctly detects pre-existing buffs active at pull (e.g. Battle Shout) and passive talent effects like Blood Frenzy (derived from Deep Wounds uptime).

Mechanic Execution Scores how well you avoided boss mechanics. Each hit is classified as critical, major, or minor.

Death Recap Full death analysis showing what killed you and the last damage events leading up to it.

Actionable Insights Specific improvement suggestions grouped by priority: Fix (critical issues), Improve (optimizations), and Tip (minor gains).

RPS Scoring

The Raider Performance Score (RPS) combines a Performance Grade (90%) and a Required Elements Grade (10%) into a single 0-100 score for each encounter.

Performance Grade (90%)

Four categories are each graded 1-5 then weighted:

Parse 35%

WCL parse percentile

599-100

495-98

388-94

280-87

Mechanics 30%

# of avoidable mechanic failures

50 fails

41 fail

16+ fails

Deaths 25%

50-2

43-4

35-6

27-8

19+

*A wipe event is triggered after the main tank dies and the raid fails the encounter.

Required Elements (10%)

Pass/fail checks. Your RE score is the fraction passed. Weapon buff only applies to classes that use oils, stones, or poisons - classes without an applicable weapon buff show x/5 instead of x/6.

Sapper used No gear issues Weapon buff* Pots used Flask or elixir Food buff

* Oil (casters), sharpening/weight stone (warriors), poison (rogues). Not applicable to all classes.

Final Score

The overall RPS is calculated as:

RPS = (Performance weighted avg / 5) × 90 + (RE passed / total) × 10

Letter grades: S 95+, A 85-94, B 70-84, C 55-69, D 40-54, F <40

Dr. R.L.D: Features

Raid Scorecard

All players grouped by class with their grade, DPS, and score visible at a glance. Players with issues are highlighted with a red glow border so problems are immediately visible.

Player Cards

Click any player to expand a detailed breakdown: per-fight scores, consumable compliance (Flask, Food, Weapon Oil/Stone/Poison, Pots, Sapper), gear issues, deaths, and mechanics.

Sapper Tracking

Detects Goblin Sapper Charge and Super Sapper Charge by querying cast events directly from WCL. Each player is counted once regardless of cast count or resists. Usage appears as a green/red tag per player, an X/Y bar in Boss Debuff Uptimes listing who missed, and a red glow on the scorecard for non-users.

Raid Debuff Uptimes

Tracks key raid-wide debuff uptimes on the boss: Sunder Armor, Faerie Fire, Curse of the Elements, Blood Frenzy, Judgement of the Crusader, and more. Shows who is responsible and highlights low uptime.

Consumable Compliance

Checks flask, food buff, battle/guardian elixirs, weapon buffs, pre-pot, and combat pot usage per fight for every player in the raid.

Drums Effectiveness

Tracks drum casts, buff application success rate, average players hit per cast, and greater vs. regular drum usage.

Gear Issues

Detects missing enchants on major slots, empty gem sockets, and below-tier gear.

Resistance Checks

Auto-detects encounters requiring specific resistances and audits each player against the threshold. Covers Hydross, Leo, Mother Shahraz, Illidan, and more.

API Settings

Both Dr. R.O.T and Dr. R.L.D use the Warcraft Logs API to fetch raid data. You have three options:

Server Default (no setup needed)

Uses shared server credentials. Works out of the box, but has shared rate limits across all users.

Your V2 OAuth Credentials

Create your own WCL application at warcraftlogs.com/api/clients. Enter your Client ID and Client Secret in the settings panel. This gives you your own API quota and avoids shared rate limits.

1. Go to the WCL API Clients page (link above)

2. Click "Create Client"

3. Name it anything (e.g. "Log Rx")

4. Set redirect URL to https://localhost

5. Copy the Client ID and Secret into Settings

Your V1 API Key

If you have an older V1 API key, paste it in settings. This uses the legacy REST API as a fallback.
