SplitWatch

Auto-split a 10–40 man raid into 2 balanced teams for split-mechanic encounters.

[!TIP] Sources de poids disponibles :

Details! / Recount / Skada — DPS + HPS live (le plus précis, recommandé)

Item Level (inspect) — pas besoin d'addon tiers, utilise l'API Blizzard NotifyInspect. Inspecte chaque membre du raid (~1.5s par joueur, portée 28y)

Manuel — sliders 1–100 par joueur sur l'onglet Joueurs

Si aucun damage meter n'est chargé, le mode Item Level est un excellent fallback sans dépendance — il classe les joueurs par stuff plutôt que par performance, mais reste bien plus informatif que des poids manuels uniformes.

What it does

SplitWatch reads your raid roster, runs a snake-distribution algorithm balanced across tanks, healers (by HPS) and DPS (by damage), then applies optional team-composition constraints (battle-rez per team, Bloodlust per team, melee/ranged ratio, dispels…), and finally reassigns subgroups in one click via SetRaidSubgroup. Made for split-mechanic boss fights — Spirit Kings (MoP), and any other encounter that asks the raid to fight as two halves.

0 required addons — SplitWatch works standalone. Details!, Recount, and Skada are optional integrations: when loaded, the algorithm reads live DPS+HPS from them. Item Level mode uses Blizzard's inspect API for a zero-dependency stat-based ranking.

Sister addon to BossWatch and TankWatch — shares side-tab navigation, gold-accent UI, and the family colour palette. Click between the three from the left edge of any panel.

Features

Roster scanner — reads your raid via GetRaidRosterInfo + UnitGroupRolesAssigned, infers role (TANK / HEALER / DAMAGER) and class
Snake-distribution algorithm — tanks alternate, healers snake-distribute by HPS, DPS snake-distribute by damage; weakest player fills the gap on the larger team for uneven raids
Team-composition constraints (Raid-Leader toggle, applied AFTER the snake distribution with minimal-disruption swaps):
- ☑ Battle Rez per team — Druid / DK / Warlock / Hunter / Paladin / DH (default ON)
- ☑ Bloodlust per team — Shaman / Mage / Hunter / Evoker (default ON)
- ☐ Balance melee vs ranged (class-based heuristic)
- ☐ Mass Dispel per team — Priest
- ☐ Decurse per team — Mage / Druid / Shaman / Monk
10-to-40 man support — subgroups assigned dynamically (1 vs 2 / 1+2 vs 3+4 / 1+2+3 vs 4+5+6 / 1+2+3+4 vs 5+6+7+8)
Five weight sources — Details!, Recount, Skada, Item Level (inspect), Manual sliders. Unavailable sources are greyed out and disabled in the dropdown.
Live source preview — verify your damage meter is feeding data before computing a split; shows live DPS/HPS values for every roster member (or for all tracked actors when solo)
Before / after preview — see each team's tank count, healer count, DPS count, total DPS score and total HPS score before applying. Per-player suffix ([ilvl 432] or [245.6k]) next to each name.
Permission-gated Apply — only leader/assistant can mass-move; combat-locked SetRaidSubgroup calls deferred until PLAYER_REGEN_ENABLED
Resizable options panel — drag the bottom-right grip; size + position persisted account-wide and clamped to current screen at load
Tabbed options panel with collapsible sections, per-section reset button, page-level scrolling, Escape-to-close
Built-in test mode (simulated 20-man roster) to preview the UI without a real raid
Multi-toc — single zip installs on Retail 12.x AND MoP Classic 5.5

/splitwatch is available as an alias for /splitw.

Configuration

Open with /splitw. Tabs:

Réglages (Setup) — general toggles (minimap icon, confirm-before-apply, summary-on-apply, auto-refresh), DPS source picker with live preview + Item Level scanner button, permission status
Joueurs (Players) — team-composition Constraints (5 toggles described above) + per-player Manual weight sliders (1–100)
Aperçu (Preview) — Compute / Apply / Toggle test buttons, source-used line, Before/After stats blocks, Team A / Team B columns with names + ilvl/DPS suffix, warnings panel (uneven teams, missing tank, unsatisfied constraint…)
À propos (About) — logo + version + author, slash commands list, panel opacity slider, reset window position, full changelog

How the split works

Tanks alternated 1→A, 2→B, 3→A … so each team has at least one
Healers sorted by HPS descending, snake-distributed (each healer goes to whichever team has the lower healing score so far)
DPS sorted by damage descending, snake-distributed the same way
Size rebalance: if |#A − #B| > 1, the weakest DPS migrates to the smaller team until the gap is ≤ 1
Constraint pass: for each enabled constraint, if one team lacks a matching class, swap the closest-score DPS pair to satisfy the rule. The melee/ranged equaliser swaps melee↔ranged DPS until counts differ by ≤ 1.

Apply pushes everyone to their target subgroup with a 150 ms throttle. If you're in combat, the queue waits for PLAYER_REGEN_ENABLED (Blizzard combat-locks SetRaidSubgroup since patch 4.0.1).

Optional integrations

Addon	What it provides
Details!	Live DPS + HPS via `combat:GetActorList(1 / 2)`
Recount	Live DPS + HPS via `Recount.db2.combats[cur].Fight`
Skada	Live DPS + HPS via `Skada.current.players`
Blizzard inspect API	Average item level via `NotifyInspect` + `C_PaperDollInfo.GetInspectItemLevel` — built-in, no third-party addon needed

Without any of the above, the algorithm uses the per-player weight sliders on the Joueurs tab (default value 50 / 100).
