Sure PvP will become more valuable as a source of Dili. This will lead to:

1. More players coming just for the dili.
2. Some of these new players will be wiped a few times, and then become regular AFKers.
3. Some will face similarly inexperienced players, and will have a blast of a n00b fight, allowing the monster of PvP addiction to sink it's claws into them!
4. = Profit!

(That said, I believe s7 will also introduse some other ways of making Dili, so maybe PvP Dili will not increase in value after all...)

What I fear is not AFKers... I fear players who will try to finish the match as soon as possible... T1 ships and no shields... charging full speed towards the enemy...
