0014311: Quaking affix algorithm not correct

Summary	0014311: Quaking affix algorithm not correct

Description	1) Bug description The quaking algorithm on this server is: Do quaking every 20 seconds. However, the algorithm instead should be: Every 20 seconds there is a chance of quaking. 2) Proof: Official server video Example video from official server: https://youtu.be/26fm5wxVhCI?t=63 (Note that timestamps are not the actual video timestamps but remaining time for the dungeon timer.) Quaking at 34:10 dungeon timer remaining Quaking at 33:50 dungeon timer remaining No quaking at 33:30 dungeon timer remaiing Quaking at 33:10 dungeon timer remaining In this example you can see that a quaking had the chance to happen at 33:30 but it did not happen. 3) Proof: Argusx100 video To show that quaking has a 100% rate on this server, here is the first part of an Argusx100 Cathedral key: https://www.youtube.com/watch?v=cLzKD6I3qwo These are the timestamps (remaining timer) for quaking. You see that it happens every 20 seconds. 34:40 34:20 34:00 33:40 33:20 33:00 32:40 32:10 (+2 deaths) 31:45 (+1 death) 31:25 31:05 30:45 30:25 30:05 29:45 4) Correct Algorithm What is the chance of quaking to be triggered on the official server at 7.3.5? I haven't found a documentation. What I did instead was to collect warcraftlogs. I've picked 17 logs containing the quaking affix with the following requirements to make the research easier: - The player has not died during the dungeon (as a dead player can't have quaking debuff) - The dungeon does not contain scripted sequences where quaking is never triggered Then I did the following math: How many seconds does the dungeon last? Example: 1459 seconds How many "20 second" intervals does it have? Example: 1459 / 20 = 72,95 => Take Math.Floor => 72 How many quakings did appear? Example: 55 => The avg. quaking rate is 55/72 => 76% For all 17 logs the avg. quaking rate turned out 77% I understand that 77% might not be the real chance of quaking as 17 examples is still a pretty low amount, but the real chance must at least be close to 77%. Therefore I suggest to change the current quaking algorithm from "Do quaking every 20 seconds" to "Every 20 seconds there is a (close to number 77)% chance of quaking to be triggered" Here is the warcraftlogs data I've used. The format is: Link Player name Total dungeon time in seconds Number of 20 sec intervals Number of Quakings Quaking average (Number of quakings / number of 20 sec intervals) https://www.warcraftlogs.com/reports/qTzYcv3DHpZQy9BJ#fight=1&type=auras&spells=debuffs&ability=240447&source=1 Stom 1459 72 55 0.7639 https://www.warcraftlogs.com/reports/MWvcbmt61hDVPH3T#fight=1&type=auras&spells=debuffs&ability=240447&source=1 Quanti 1624 81 59 0.7284 https://www.warcraftlogs.com/reports/DJ2ZFb9vfcP6a3RN#fight=2&type=auras&spells=debuffs&ability=240447&source=2 Littlealby 832 41 32 0.7805 https://www.warcraftlogs.com/reports/qVW8zwZnbx4amL13#fight=1&type=auras&spells=debuffs&ability=240447&source=1 Padadave 1148 57 45 0.7895 https://www.warcraftlogs.com/reports/H1RcMK8fvnDqQb3g#fight=3&type=auras&spells=debuffs&ability=240447&source=75 Анава 1193 59 40 0.6780 https://www.warcraftlogs.com/reports/L9d2FZj34ytqNHYw#fight=33&type=auras&source=12&spells=debuffs&ability=240447 Dotsnothot 812 40 33 0.8250 https://www.warcraftlogs.com/reports/X3HT1ZV4fWJdarM6#fight=1&type=auras&source=4&spells=debuffs&ability=240447 Deathnahcz 1204 60 47 0.7833 https://www.warcraftlogs.com/reports/B9f8KM43QA6v1jLy#fight=2&type=auras&source=2&spells=debuffs&ability=240447 Merajin 1307 65 51 0.7846 https://www.warcraftlogs.com/reports/fk7Kavrzm3b62FGP#fight=34&type=auras&source=3&spells=debuffs&ability=240447 Trif 1199 59 43 0.7288 https://www.warcraftlogs.com/reports/B9f8KM43QA6v1jLy#fight=3&type=auras&source=2&spells=debuffs&ability=240447 Merajin 1461 73 62 0.8493 https://www.warcraftlogs.com/reports/AvQwP9XxYNL6bt8M#fight=22&type=auras&source=18&spells=debuffs&ability=240447 Klaps 1558 77 60 0.7792 https://www.warcraftlogs.com/reports/FykjDYpKPmxBdTf9#fight=5&type=auras&source=2&spells=debuffs&ability=240447 Nishizumi 1060 53 41 0.7736 https://www.warcraftlogs.com/reports/8KBt1AJry4a6jhbk#fight=8&type=auras&source=4&spells=debuffs&ability=240447 Baseddhunter 1143 57 46 0.8070 https://www.warcraftlogs.com/reports/haH1JRvDFnPcz7Qj#fight=33&type=auras&source=69&spells=debuffs&ability=240447 Shabooke 1036 51 37 0.7255 https://www.warcraftlogs.com/reports/ygGh8W1vTMJXk6bL#fight=1&type=auras&source=4&spells=debuffs&ability=240447 Crescentsoul 1157 57 45 0.7895 https://www.warcraftlogs.com/reports/GmdZ7fNhPvnT8Qxy#fight=3&type=auras&source=146&spells=debuffs&ability=240447 Fortyseven 1214 60 49 0.8167 https://www.warcraftlogs.com/reports/caRyvmMwbrHA2XnD#fight=26&type=auras&source=15&spells=debuffs&ability=240447 Psicosi 1373 68 41 0.6029
