Ok, I expect some flamage for this, but before you flame, at least give it a read, I will keep it short.
I am not suggesting opening up the quests in the paid wilderness areas. First and foremost on that.
I am suggesting to open up all the wilderness slayer areas to F2P so that new, returning, and existing F2P players can just get into the zones, and see what it is about.
I think sales of the 'quest packs' for the zones would likely go up if F2P players got the chance to see, hear, experience, and chat about some of what they are missing in the zones.
They wouldn't be getting into the raids/quests that are in the zones unless they did buy the quest packs, so there would be little harm.
Take Reaver's Refuge. You can get some kills, some rares, and some runes that are completely useless to you and waste your bank space unless you complete SoS right? This may sell more quest packs for the zone, and also more bank slots as well.
Same for Sands, you can farm for some gar in the wilderness area, but you cannot upgrade it without getting the packs.
I think including more F2P players into the general area, as far as a business model, would be a means of increasing overall sales myself, not to mention that you have shown you can do this with Delera's Graveyard, it is open to all pay styles, but the quests are locked out.
Well, a good day to all, time for my 9 to 5 to start.
