Crota's End Heroic in its prime sheerly because it was rng reliant: -Heavy Ammo drops -Boomers -Corta harassing the sword guy -Swordbearer can -blam!- off into the room below the crystal and hide there -Accidental player death -Orge slammed in the room -Ogre killed someone unaware in the ogre room -Had a bad sword runner -Crota would get up too early sometimes -Cursed thrall -No shield/health regen other than helmets with perks, red death and suros regime Need I go on? And this was when this raid was hard, not now where you can solo it easily.
