Do you see a lot of people (not bots) making regular rounds looking for IDOCs now? This is when they are given 15 or so hours to find it. If you switch it to no warning, it would be impossible to traverse even a single shard before the items will decay. No sane person will do something with such a small chance of finding a house before items decay. But it's still worth it for the bots, because they have all the time in the world.
So you will go from a situation where scripters collect the bulk of the stuff, but regular players still have a chance to grab something, to a situation where regular players have no chance at all.
NO because even if you FIND an idoc now there is no point in camping it, you don't know when it is gonna fall and you don't have 15 hours spare to sit and watch it and you can't compete with the bots and scripters that have been camping them even if you take the time.
The idea is to make stumbling across a fallen house fun and equal to everyone. Those that wanna spend the time treasure hunting for idocs can, run the lands, guilds can split up 'areas' to check, those that live next a place that falls are 'lucky' those that stumble across places are also lucky. Increase the decay rate on items if you must, to say 24 hrs on IDOC items only.
Take the 'business' part out of it. Right now IDOCs are predominantly for those illegal sites who flog off stuff for real life money. The ONLY shard that this doesn't apply to is siege where player justice sorts it out. On production shards it is set up by scripter for scripters, I have NO doubt someone is making a pot load of real life money on this issue and that is why it is never changed. The last change they made actually made it even BETTER for scripters so yeah, I have no doubt no change will happen.
I don't have any problem with it 'being impossible to traverse even a single shard' as frankly it should never be able to be done anyway. What happens now is the scripters run all shards, place their bots, get their times then pick the choice properties on each shard, castles, luna plots, keeps, those plots that have been established for yrs, place their bot scritpers to watch the signs, then get their camped out looters to arrive minutes before the drop to scoop everything up. The castles on our shard are always camped by offshard scripters when they go idoc, as are the luna spots. The ONLY people doing this type of operation are the well knowns cheaters.
I would rather people are able to get a bit of luck and score rather than keep going with this farce we have at the moment.
