Spell Queue Window & GCD Latency Engine v1.0

I built this to end GCD clipping debates with numbers. Drag the sliders. I divide base GCD by your haste, price ping against your queue window, and hand you the exact in-game macro.

Class Cast Model

Energy GCD stays pinned at 1.0s — haste never moves it. Melee shares the 1.5s base and 0.75s floor; instants only skip the cast portion. Bloodlust multiplies current haste by 1.3.

CLIPPING RISK: Queue Way Above Ping.

Default 400 ms on a 45 ms ping overwrites procs on double-taps. Paste the macro above and re-check the log for GCD clipping.

Math I use: GCD = max(0.750, base / (1 + haste)). Optimal queue = ping + 40 to 60 ms hardware buffer, capped at 400. Bleed = dead-time / GCD priced per pull.
