Hey guys, not sure if this belongs to exploits or the guides section, but I'm pretty sure this is not intended by Blizzard,m so I'll post it here. Feel free to move if a mod finds it really inappropriate.
So, when you have the Baracks as a level two building or higher, you can assign five followers as a bodyguard. One of them, a restoration shaman named Leorajh will cast Bloodlust on you once you're exalted with him. This bloodlust does not appear as a buff, neither does it give a debuff, but you can quite notice it by the visual effect around you.
Blizzard is not allowing bodyguards in Ashran, as it would give an unfair combat advantage, however:
Leorajh seems to be bugged, and whenever his cooldown from Bloodlust is ready,m he will spawn and cast it on you, granting you the haste effect.
TL;DR version:
1- Have Barracks level 2 or higher
2- Be exalted with Leorajh (check fast rep grinds for followers, did mine in 15 mins)
3- Make sure you have Leorajh active when you join Ashran
4- Enjoy personal Heroism/Bloodlust whenever available. You need to do nothing, he will just spawn and cast it and disappear again.
Edit: The exalted perk is Garrison Mission access anywhere, the Bloodlust might not require you to be Exalted with him, but one rep level below it. I don't remember when the Bloodlust buff is gained.
