I just want to say that I doubt this very much. You don't see players on Siege because they are out hunting or doing stuff. Most people don't sit around AFK at the bank on Siege because if someone like me finds you doing that you're going to return to an empty pack. Also, Siege is not really the dedicated PvP shard as people like to pretend. There are a handful of people there that will kill you if the see you, but the large majority are just there to run the PvM content and craft (because crafting is still a viable profession there). They play on Siege because they feel accomplished when they do something, the feeling is just not the same on production shards. The feeling of accomplishment is what is meant to be fun, not the acquisition of stuff. The PKs are what provide that feeling, so next time you see one, tell him "thanks."
Also, I love the fact that these threads always lead to people saying that the majority of players don't want to PvP which I believe is entirely false. I believe that most people that enjoy PvP have left to go to free shards because the devs are as short sighted as those that make these claims. If you look at free shards, there are more non-consensual PvP shards than anything else. The most popular free shards are PvP enabled. The only reason that the vast majority of players only do PvM content here is because the devs here don't make content for PvPers.
That being said, if the devs wanted more subscribers, they would increase the amount of PvP content and not worry about Whiney McWhinington over on that other thread who claims to have quit (which was proven false). Nobody is quitting because they can't get scrolls, because that is a blatant lie, they only say that to try to get kind-hearted fools like
@celticus to jump up and advocate for them with silly ideas like the one proposed here. If people are really quitting over this, I say good riddance as the last thing the game needs is more entitled crybabies taking to the internet and spreading lies about how things are for their own personal gain. If you want to do what is best for the game, encourage people to take a risk to get the things that they think they need and stop spoon-feeding them.
