I like PvP and I am happy to see it being added for those of us that enjoy it. They are keeping it to its own areas and it is completely optional.

For PvP I think it would be cool if they had arenas that people could watch, so even if you aren't interested in doing PvP you can still watch two people have at each other! Maybe add /popcorn emote!

I'm not sure they if they are doing this or not, maybe they are? They could also add in components to the PvP areas that you can participate in without actually fighting other players - such as repairing buildings/equipment or gathering materials or other stuff. I know GW2 has things like this which seems like a really good idea for those that aren't interested in fighting.
