Dark Souls Reveal

So I play this game called Dark Souls sometimes and I was doing some invading in this place called Anor London I was using this character that uses a Dragon Greatbow and I go up to this place where there are 2 NPCs who also have Dragon Greatbows. This way when the person tries to pass they have 3 Dragon Greatbows firing at them instead of 2 for more fun challenge. I also have Great Combusion Fire Pyromanncy in case they get close.

I just wanted to know if this is okay or not
