I wanted to pitch this idea it may be fun.
This is dark souls inspired.
Imagine if you could invade a 5 man dungeons and 1v5 groups for a short time.
It would be an opt in/opt out sort of mechanic with higher rewards for those who choose to allow invaders.
You would be at a great disadvantage as an invader and would need to time your ganks properly. I think this would be very interesting and make every dungeons experience different from the last…
Generally most people who do PvE content want it to remain as PvE.
Blizzard would have to make the Invader ‘friendly’ with every mob in the instance, drop them off at a different spot in the istance every time because once it became common knowledge of a spawn point the 5 man would just destroy the literal 1 person who thinks they can do anything against a party.
Don’t do this. They need to focus on bug fixes and class tuning before even thinking about putting PvP in what has always been PvE content.
