Around the time we put the ranger revamp in, we talked a bit about how the orc adapt changes were shaking out, and how orcs would be doing with some rangers moving into what were "their" terrains. As a result:

1) Brute Force was toned up a bit.

2) Shig-ru Berserk has added offensive and defensive benefits.

Both of those were done by Valg around that point and have been live for a while, but I'm pretty sure we were waiting on the next one to announce them.

3) Orcs can see hidden and camouflaged characters, as long as they're in the same room as them, and as long as they're in a terrain type the orc could hide in at that level.

That one'll be in next crash or reboot or so.
