Summary: Pets have a significant issue with lag in most modern raids. In many of these situations, they swing at a significantly slower rate than they are intended to. It's not uncommon to see 10+ seconds in between pet swings. This drastically reduces their DPS output, both from melee DPS and from procs. This only happens to "main" pets; swarm pets do not appear to experience comparable lag. ______________________________________I originally made a post about this issue here, and it was the highest voted unresolved bug on the issue tracker prior to it going down. It's been an issue since at least TDS, and has worsened as zone performance has generally deteriorated. It is common for pets to swing at fractions of the rate that they "should" swing at, compared to swing rates on Combat Dummies or in group content.First, here is a parse from a combat dummy to demonstrate expected behavior (709 second duration):Puksu -vs- Combat Dummy Meda II: -- DMG: 33827211 -- DPS: 47711 -- Scaled: 47711 -- Slash: 24513237 -- Backstab: 8700668 -- DirDmg: 613306 -- % dmg as normal: 21.3% -- % dmg as critical: 78.7% -- Non-crit rate: 55.4% -- crit rate: 44.6% -- Attempts: 2736 -- Hits: 2530 -- Missed: 206 -- Accuracy: 92.5% -- Avg Hit: 13370 -- Max hit: 131770 -- DMG to PC: 02342 of those attempts were slashes, which equates to 3.3 attempts per second. Here were my pet's casts:Combat Dummy Meda II on 10/25/2019 Puksu (Sancus) - 185 --- Iceflame Strike Caza VIII - 97 --- Water Elemental Strike XII - 88 That's an iceflame proc every 7.3 seconds under normal behavior. Water Elemental Strike cast every 8.05 seconds. Both of these metrics are without Frenzied Burnout; slash attempts would be higher were it running. To compare, here is some data from recent TBL raids. I want to begin with the graphs because they illustrate how severe the problem is - there are multiple 30+ second gaps in between pet melee attempts on this graph.Digging into the numbers from the latter graph (Aalishai), here is my pet's melee and cast parses:Puksu -vs- Seneschal Radiant Propensity: -- DMG: 5595533 -- DPS: 19912 -- Scaled: 18903 -- Slash: 2452563 -- Backstab: 1605279 -- DirDmg: 1530264 -- Environmental: 7427 -- % dmg as normal: 44.5% -- % dmg as critical: 55.5% -- Non-crit rate: 62.6% -- crit rate: 37.4% -- Attempts: 133 -- Hits: 115 -- Missed: 4 -- Defended: 14 -- Accuracy: 96.6% -- Avg Hit: 48656 -- Max hit: 438053 -- DMG to PC: 1383939 Seneschal Radiant Propensity on 10/6/2019 Puksu (Sancus) - 26 --- Arcane Ballad Strike III - 4 --- Companion's Assault XXXI - 4 --- Iceflame Strike Caza VIII - 2 --- Storm Blade Strike - 4 --- Travenro's Strike III - 1 --- Virulent Talon Strike IV - 10 --- Water Elemental Strike XII - 1 Here's a comparison between my combat dummy parse (which did not have FBO): Instead of making 3.3 slash attempts per second, my pet made 0.3 slash attempts per second (89 of those attempts were slash attempts). In other words, he swung at about 1/11th the rate he should have. Iceflame averaged a proc every 148 seconds, as compared to a proc every 7.3 seconds. Water Elemental Strike cast every 29.6 seconds, as compared to a cast every 8.05 seconds. Virulent Talon did not consume all 15 of its procs over the 5 minutes this fight ensued. This really hampers pet class DPS in raids, and also contributes significantly to the variability in our DPS. This makes tuning pet-based upgrades extremely difficult, because many of them have almost no impact in raids. Despite numerous upgrades to pets, their sustained DPS in such situations is below what it was in Call of the Forsaken. I know zone lag is a very difficult issue to fix, but it's extremely detrimental to the experience of raiding in EQ, and it seems to be a bug that zone lag causes "main" pets to skip swings (whereas normal melee and swarm pet melee do not). I appreciate your consideration.
