Yes, many people hate Heroic PVEs. This is because you are limited to using a small amount of weak characters, while the enemies are able to use very strong characters.
But what about Heroic PVPs? We could limit the characters everyone would use, and that would place them on the same level. You could even exclude all 5s, so 4s are the best characters.
This would be better than the PVE, because there wouldn’t be any crazy scaling, as everyone would have access to the same set of characters at the same level. It would be a good change to the regular PVPs to do this every now and then.
