Currently the TIMERS feature just aggregates abilities by spellId, however Here is a pretty strong example where timers aggregated by spellID AND enemy would come in very handy.. Do it by GUID and you could even split timers by add spawns (although I'd limit it to adds important enough for a boss unit Id)

["203028-Corrupted Breath"] = "pull:15.5, 1.2, 29.2, 6.1, 27.2, 0.8, 27.1, 6.9, 21.1, 13.0, 27.1, 6.9, 21.0, 13.0, 16.2, 11.0, 18.3, 16.6, 11.4, 22.7",
Which tells you very little
