I play as a gimped whm and made a thread, sure i may have a seemingly harder time but imo it makes the game more challenging in a way and it allows me to cheese content.
So imo hardcore ppl are ppl who don't care about nerfs and just play the game the way they want even if it is looked down on, they are hardcore so they'll make it work out and possibly find new ways for others to be enlightened.
Enrage t2 was found because a person thought of it and shared it.
Now it's a widely known useful tactic.
