WoW Boss Mechanics explained

An Explanation on the different types of Boss Mechanic (scripts) and why Bossmods can't predict everything perfectly.

There are two major types of how the Boss Mechanics were implemented

1. Timed Mechanic
   That's basically what everyone think of all the mechanics - which is just wrong.
   Timed Mechanics do come regularly, after time x. That means such mechanics can be predicted 100% precisely all the time. Sadly most Mechanics do not work like that.
   An example for bosses using plain Timed Mechanics : Firemaw / Ebonroc / Flamegor
2. Spell Cooldowns
   This one is more commonly used, it is also as simple as I named it - Cooldowns.
   Such Mechanics will not always come at the same time and therefore you can't predict them precisely.
   While Timed Mechanics come after time x, those can come after time x but can also come after time x+15 or x+20 and so on.
   The only way a Developer could create a Bossmod timer for that would be a 'Cooldown' timer with a value gathered on video footage which must not necessarily be perfect (you simply can't tell exactly what x is, you can only take a guess judging by the video footage you have access to and take eg. the lowest value)
   An example for bosses using Spell Cooldowns: Razorgore / Bloodlord Lashlayer
