I just completed the Crimson Nirnroot quest in Blackreach. It made me wonder just how big that place is. Here is an overlay to give you an idea.

Ordinator nerfs stealth bonuses a little IIRC, and offers branches that give buffs for repeated short range arrow attacks. It also allows a whole host of previously impossible builds in nearly all skills.

Archery tree:

0 - Archery Mastery (2) - Bows and crossbows deal 20/40% more damage./, and critical strikes with bows and crossbows do 2% more critical damage per level of Archery.
20 - Clean Kill - Bows and crossbows deal 20% more damage to a target at full Health.
20 - Wingstrike (2) - Bashing with a bow always staggers the target. Bows and crossbows deal 20/40% more damage to that target for 10 seconds.
30 - Long Shot (3) - Bows and crossbows deal 10/15/20% more damage for each 25 feet beyond the first 50 feet, up to 40/60/80%.
30 - Steady Hand (3) - Pressing Block while aiming will zoom in your view/ and slow time by 25/50%.
40 - Crippling Shot - Arrows and bolts slow a target within 25 feet by 10% for 20 seconds. This effect stacks.
40 - Hunter's Discipline - Recover twice as many arrows from dead bodies.
40 - Thread the Needle (2) - Bows and crossbows ignore 25/50% armor if the target is not moving.
50 - Pinning Shot - Arrows and bolts have a chance to stagger a target within 50 feet. More effective against targets with a lower remaining Health percentage. No effect on massive targets.
50 - Ranger - Can move at full speed with a drawn bow.
60 - Quick Shot - Can draw a bow or reload a crossbow 30% faster.
60 - Snipe - Shooting targets you haven't shot within the past 10 seconds inflicts a critical strike that deals five times critical damage, and any weapon enchantments applied by the shot are twice as effective.
70 - Ambush Predator - After standing still for 6 seconds with a bow or crossbow out, it does 25% more damage until you move.
70 - Focus on the Prey - Cannot be staggered while holding a drawn bow or reloading a crossbow.
70 - Thieving Raven - Enemies within 25 feet are disarmed when shot during their power attack.
80 - Deadeye - Grants the "Deadeye" power. Once a day, slow time and focus on your foes for 10 seconds, looking for opportunities for a killing shot. Finding their vulnerability takes 1 second per 125 Health. Once you do, you may shoot them for an instant kill.
80 - Hailstorm - Attack 8% faster with bows and crossbows for 10 seconds after shooting a fully drawn bow or crossbow in combat. This effect stacks.
80 - Trick Arrows - Able to upgrade many types of arrows at a forge or anvil, adding a bonus effect (Force, Immolation, Freezing, Grounding, Maze or Death) based on its material.
90 - Hunt Together - When fighting only one enemy, hitting the target with a bow or crossbow manifests a Spirit Wolf for 30 seconds. The wolf deals damage equal to 15% of your current Stamina. This effect has a 30 second cooldown per target.
90 - Three Crows - Shooting a target beyond 25 feet three times, leaving less than 2.75 seconds between each hit, deals bonus damage equal to 15% of the target's current Health (max. 150 damage) and knocks the target to the ground.
100 - Perfect Aim - Bows deal 25% more damage if the shot strikes a target within 2 seconds after the bow is fully drawn. Crossbows deal triple damage to targets with 20% or less Health remaining.
