Hardcore World

[StrejdaTom]

The op basically wants A3S abd A4S difficulty in the open world. Tons of people quit because that is too hard for them.

Why would this be a good idea to implement again?

How can any open world mob have savage difficulty? Most of the mechanics are built on team coordination and being positioned in small arena.
Harder difficulty on mobs that are positioned in open world could mean that they would have more HP, do more DPS, do high amount of AoEs that would give you only a second to dodge and would require you to save cooldowns to kill them alone and maybe have skills without castbars so you would actually have to watch the mob. But saying they would have savage difficulty is nonsense. They wouldn't implement a normal mob that would take you weeks of training to kill, we are still talking about open world mob.
Even mobs in Diadem that were supposed to be hard are just huge HP bags which posses absolutely no threat to anyone.

EDIT:
Plus I am pretty sure it isn't even possible at this moment to have open world encounter that would use mechanics aimed on different people who wouldn't even be party members. Stuff like Carnage in A4S or tethers in A3S. I believe you have to be in a party and a separated instance which registers you as a single party to be able to be influenced by such "savage" skills.
