My HR build Mk2 :)

1st off I have chosen Half Orc and taken the Pathfinder Path.

At-Wills I use Rapid Shot and Aimed Shot. Aimed shot is good at 1 shotting a lot of lesser enemies, plus the melee version can inflict bleed which is very nice sometimes. I actually use the bow (Golden Dragon`s Smile) which increases my run speed after an Aimed Shot so I start off most fights with it, the bow also increases Aimed Strike damage.

For class features I run with Aspect of the Pack for the combat advantage bonus and Aspect of the Serpent. AotS is a must for me as it increases damage by quite a bit by stacking buffs on Melee when using ranged powers and vice versa.
I also take the Off-Hand Class Feature which increases AotS even further and the Off-Hand Stat Increase is +391 Combat Advantage.

Dailies I run with are Slashers Mark, it does quite a large bit of damage whilst buffing other players who hit the target. It is actually really useful when you dodge a lot against certain enemies like LoL Scorpions or LoL boss himself. The other daily I use is Seismic Shot, hits really well when a crit and buffed up with AotS. Both of these Daily powers should be used at the start of a rotation (just after switching stances) to maximise all the buffs they get, if you are in ranged stance use Seismic Shot, if at the start of a melee rotation then use Slasher`s Mark.

For Encounter Powers I use Fox`s Cunning, this is amazing. It gives your whole team a free dodge when in ranged stance and the melee version is the nuts, it hits multiple enemies multiple times. Also the melee version increases your run speed while reducing the enemies. Also you can trigger other Abilities whilst in mid-animation and also fire off your At-Wills during the animation.

Next Encounter is Hindering Shot, this is a must for my Trapper HR, it has 3 shots with separate cool down, plus Grasping Roots on both the ranged and melee versions. The melee version is Strong Grasping Roots which this class excels at.

3rd Encounter is Binding Arrow for the above reason (Grasping Roots), the melee version Oak Skin Heals your entire team and buffs their defences. Now if you are running in a group then using Oak skin will pretty much reset your ranged encounter powers, same with Fox`s Cunning when used in a group will pretty much reset your ranged encounter powers.

For Feats I have spent the Heroic Points like this :
5 Predatory action = 5% increased damage to Daily Powers
3 Weapon Mastery = 3% Crit Chance
3 Toughness = 9% more HP (now Draconic Templar armour is out this is worth it)
3 Agile Combatant = 3% more damage when switching stances
3 Endless Assault = 6% more damage from Encounter Powers
3 Disciple of Dexterity = 6% damage bonus from Dex

All my points go into the Trapper tree as its just that good :
5 Readied Stance = 5% AP regen when switching stances
5 Deft Strikes = 10% extra damage for melee encounter after using ranged encounter and vice versa. Also for me this is a must for this build.
5 Ancient Roots = 2.5 seconds more for weak grasping roots, 5 seconds longer for strong grasping roots.
5 Swiftness of the Fox = 15% shorter cooldowns for the melee encounters when using ranged and vice versa. This is the best thing to put points in, you almost have no cooldown times when using all the encounters before switching.
5 Thorned Roots = Grasping roots now does 200% weapon damage to target every second, if they are immune to grasping roots it does 250% of weapon damage.... nuts
5 Serpents Bite = Aspect of the Serpent now does 5% more damage per stack + 2.5% crit chance per stack.
