The matter of barging is a nonissue. Us not being able to barge in is no biggy as long as they can't barge us out.

It's just the attacking people in another area that is. And if we back off, what we end up doing is having the attacking forces move in, killing shadowbound fae/daughters of night, and then fading back.

The only way in or out is through that channel, and if they can just butcher someone moving through it, that strikes me as imbalanced.

Something we've all dealt with and I think we all should have to deal with.

That is completely and utterly untrue.    No organisation besides Glom has been  sieged and unable to muster a defence to protect their assets. I don't have a problem with the fact that we are being blockaded, if you will. But they shouldn't be able to take potshots at us in our territory.

Celest and Serenwilde have both been sieged and been too crappy to defend themselves. It still happens sometimes for friggs sake.

I never saw that happen before I left, and I've yet to see it happen since I got back.. Going into a city/commune to raid is one thing, sitting outside and taking potshots is another. The former is what happens, the latter, not so much.

To turn the question around, is there a reason NOT to block cross-boundary attacks like that?

The later has happened before and still happens.

These troubles -should- exist for a new organisation, it should be something you should have to deal with using the same mechanics as everyone else.

I am not terribly concerned either way, but you must remember the reasons of why you would use a distance attack in the first place.  Primarily, I imagine, to avoid area attacks such as summoning, or Moon/Night rages off the top of my head.  Preventing this would be a disadvantage - not severe, but a disadvantage nonetheless.

Also, one of the best uses for distance attacks is to discourage people sitting directly outside a defended area. Generally the defenders have more of an advantage inside their defended area than the raiders do outside, so with reasonable tactics one can drive off those who lurk on your borders.

If there have been groups of a dozen or so people sitting outside the Seren mauling anyone who comes by, I certainly haven't heard of it.

As far as new organisations, it's easy to say that since.. well.. There are no other new organisations, nor have there ever been. 

That's because you're not us, so you don't know when it happens. IT HAS. I've BEEN there.

In theory, it is a good way to discourge people from sitting outside. In practice, it works for everyone else That said, the reason I support the idea Estarra mentioned is not because of our numerical inferiority. I just don't think that anyone should be able to sit outside an area and attack people inside as they're going about their business.

Most distant attacks work only in adjacent rooms, apart from damage attacks that work in line of sight.  I really don't think it is that difficult to go about your business without sidling up to the border of your domain if you aren't prepared to defend it.

Throughout this conflict today, you have been facing off against the mighty forces of TWO hartstoners.  Often just one.

Come on.

If there have been groups of a dozen or so people sitting outside the Seren mauling anyone who comes by, I certainly haven't heard of it. "Oh well, I'm not omnipotent, and that's a tangential matter anyways."
