Hopefully there'll be a mark on peoples' Search Info after using them so we know who to blame when they inevitably are laughably unprepared for even the most basic dungeon mechanics.

You want another "presumed negative effect"? Dungeons are going to have to be made pointlessly easier just to accomodate people jumping into them with no experience in the game. The alternative? Dungeons have some difficulty to them and you can get trapped into a timesink party with one or more dead weight players who, trust me, may very likely be extremely resistant to criticism / instruction from other players. I've encountered two White Mages in the level 50 range who not only didn't use Regen, but outright refused to use it when instructed to.

In addition, have fun with slower queues now that people can just skip past all of that. Users who choose not to fork over the cash to cheat their way through now have a worse experience because of it.
