Most people want epic battles and Large-scale raids are not epic sorry.
FIXED.

Large-scale PvE events only feel epic because of the amount of people involved. In reality, they are easy-mode. If I can take 20 or 30 players and just throw them at a boss mob until it dies, then there is no real challenge and it is definately not epic. Now I won't argue that Large-scale PvE events might be more fun for you, that gets down to your personal preference. But don't mistake fun for epic. Epic means heroic or majestic. There is nothing majestic about having 20 or so other people to fall back on. That implies your weak. And likewise you cant be a heroic when you and 20 or so of your friends are ganging up on something.

Imagine the hardest Large-scale PvE event yo have ever encountered, and then Imagine only 4-8 people doing it. Now imagine that the devs dont lower the difficulty, and yet you can only use a party of 4-8 people and you win. Tell me thats not an epic. Tell me thats not heroic. Now Imagine 20 or so people going to do the same event, and they win.......... How much respect do you have for their skill? I wouldnt have any for them, would you?
