Classic Why do all the main characters speak in slow motion?

I feel like Alexstrasza is the worst offender, but tons of cinematics have characters saying their lines extremely slowly and not at all how normal people speak and it's super immersion breaking. This is unique to WoW so it has to be some sort of artistic decision, but why? Who wants this? via /r/wow https://ift.tt/VXx0hgv
