There are two main problems with Unrest as it stands right now.
The first big issue (and boy is it ever), is that Ogres and Trolls (and maybe Barbarians too) suffer in Unrest's cramped quarters. They're forced to crouch to get through most of the halls indoors, which makes things difficult for them - they cannot fight while crouched and must fleed to a room with a higher ceiling. If you don't know how to manually duck, an Ogre or Troll can get trapped in Stanley the Manley's room, unable to get out the staircase due to a low ceiling in the way.
I realize you probably can't adjust the map much, but what you can do is have one of the zone quest NPCs detect when a member of a "large race" (Ogre, Troll, Barbarian) is talking to him, and have that NPC hand over a custom clicky item that does nothing but shrink the user, in order to make navigating and fighting within Unrest easier. This way, everyone can enjoy Unrest properly, not just those who are under 7' 6".
The other big problem with Unrest is that there's a couple named spellcasting NPCs, Stanley the Manley and Purity the Easy in particular, who throw around buffs and heals when you're fighting other NPCs in the building. Now this wouldn't be a problem, except that they cast through walls, floors, and ceilings to do it..
I had a crazy fight inside Unrest where Stanley the Manley dropped a heal on Master Cuddles the Executioner, despite the latter being in the execution room in the basement, and the former being on one of the building's uppermost floors!, and in several situations I've wound up taking way more damage than I should have in a fight because Purity the Easy put a damage shield on my opponent just prior to battle. Needless to say, this is really irritating.
Now, yeah, I'll admit that you could make the argument that it leads to some strategy in how you go around killing named mobs - do you really want to just blitz Chaos the Tactician, knowing that he's in casting range of Purity and Stanley, without killing the other two first? But the problem here is, these NPCs are capable of behavior a player can't match. If you attempt to cast on another player that you don't have line-of-sight to, you get an error message. These NPCs should rightfully be limited the same way. They're already formidable by virtue of being named NPCs in a low-level zone, before most players have many tools for dealing with such. The idea of them passively buffing and healing each other adds unecessary aggravation. Is it possible to remove the offending spells? Or limit them to only casting on the NPCs in their respective rooms?
I believe these two changes, taken together, would really help this otherwise fantastic and well-designed zone. This is important, since Unrest is one of the first zones a new player to the game will experience, and aside from these two issues has a fairly smooth progression for virtually all classes and combinations thereof.
Thanks for your time; I know this post is a bit of a wall of text, so if you've had the patience to read it through completely, I appreciate it.
