No idea what relevance this has, however any place has trees that a Druid wants to have trees, aside from Ethereal Glomdoring(which have trees, just not hartstone trees), and the two Elemental planes.

The relevance is that when you climb into a territory through trees the guards don't stop you.

In fact, I gotta say...isn't that the whole -point- of ranged attacks?  To stand back a distance and smite thy foes from afar?  Hence being a "ranged" attack.

And let's have a look at who has ranged attacks.
Aquamancers
Blacktalon
Geomancers
Hartstone

Guilds that can't, typically, stand up to melee combat exceptionally well in the first place.  Thus, they stand back a room or two to fight in relative safety.

Now, there's also things like Beckon, but you can *Gasp* Stand one room back in your home territory!  Make them walk into guards to do it to you!  And then, once they've walked into guards, you can run in and help the guards out!  What a brilliant strategy, why didn't someone think of that -ages- ago?  Oh wait, someone did.  That person's name is "Everyone."

I really dislike not being able to look through
the archways, so it would be nice to be able to glance
through them or glance archway and as for running in
and out of them, either make it so you can briar archway
or give entering and leaving archways a balance cost, maybe
half of what it takes to transverse?
