In World of Warcraft, you can refer to the following for the speed level of World of Warcraft:
1. The haste level means that the higher the haste level, the faster the spell casting speed. It is the most important spell attribute in the early stage and later stage. To put it bluntly, it is to reduce the spell reading time. For example, if you want to cast a spell, the reading time is 3 seconds. Then you can reduce the spell reading time by increasing the spell haste level. 15.8 points of spell haste level is equal to 1% of the spell acceleration. For example, if you have 158 points of spell haste level, then you can get 10% spell acceleration. Then a skill that requires 3 seconds to read can be reduced to 3-(3X10%)=2.7 seconds if it passes 158 points of spell haste level.
2. Every 15.7 haste level = 1% haste. 1% haste means that 101 spells can now be cast instead of 100. 100 shadow arrows of 2.5 seconds take 250 seconds. If there is 1% haste of 250 seconds, 101 can be placed. The speed of each one is 250/101=2.475 seconds. Raw speed is the speed after talent is taken into account. Taking Shadow Arrow as an example, every 1% increase in speed will increase the casting speed by how many seconds. It can be seen that the higher the haste, the actual increase in speed brought by each 1% stack will become less and less.
