"But in general, fall behind what?"
You're either being purposefully being disingenuous or the +task code has changed a ton since I was active.
The way it felt when I was still actively playing, if you're a noble, you need to be generating resources --because whatever you make, your family gets a copy of. So you either do tasks, or your entire family is going to fall behind all the other families, and then you're fucked if/when another house decides they don't like you and they're all +task spammers. Especially with all the 'NPC soldier'/NPC war stuff supposed to be coming. Hell, perhaps this is wrong, but I was told it costs resources for Noble players to get NPC bodyguards.
I mean sure. If you're just commoner joe the dress maker, you don't need to worry about tasks or resources (and uh I don't even think you have as much access to them in the first place).
It's all good and well to say 'oh people don't need to do tasks! don't be silly!' but...if you aren't, you are basically resigning yourself to be a nobody, because the other people will have way more money/etc than you and it /does/ actually impact several facets of the game.
Somebody said tasks don't generate money anymore. But, if they still generate economic resources...which you can trade for money...how much money is a task worth? Is it still more than a WHOLE GREAT HOUSE makes in a week? Because it was before.
I'd personally much rather just be able to RP building alliances and shit without a coded 'checklist' thing. My opinion of the task system is that it just waters down RP, because people aren't coming to you for RP, they're coming to you to get coded support for their task.
Edit : Further edit. The +task system provides a coded popularity contest and way to circlejerk and promotes mentality you don't really want on an RP game. The game becomes less about roleplaying with other characters, and more about getting your tasks done. Is it any surprise that players like the Gareth-guy that got banned were ALL ABOUT IT? I think there was a Redrain noble who was rabid about tasks that /also/ got banned, but I could be mistaken. Rokhir or something? He and Gareth were both the two biggest parties whining about 'omg when is the task system coming back!?' 'pls! tasks fixed yet!?' 'tasks again when!?' when it got turned off for a day or two, months ago. Not everybody is going to be as blatantly crazy about it as those two, but I feel pretty confident in saying it still severely impacts the way people play the game and the way they think about 'rp'. And I don't mean that in a good way.
