Spotlight on Legion Commander

Legion Commander is a very versatile hero, who can be played in many roles.  Despite not having a teamfight-oriented Ultimate, she could probably be played as a support similar to Abaddon or Ogre Magi, due to her ability to buff/heal teammates and nuke.

Laning LC (farmer)

Starting:  Courier, Tango, Clarity, Healing Potion, 3 Branches
Early:  Boots, Stick
Core:  Power Treads, Armlet, Blink Dagger
Core Ext:  Basher, BKB
Lategame: Abyssal, AC, Boots of Travel (BoT), Heart

Jungler LC

Legion Commander is often jungled even from level 1, because she is tanky, has early Lifesteal thanks to Moment of Courage, and can self-heal with an attack speed buff using Press the Attack.
I highly recommend Bottle with the 6.82 change to runes.  Soul Ring is also a viable option combined with LC's self-heals and lifesteal.  A Jungle LC should try to gank and snowball after L6, hence the "racecar" midgame items such as Phase and Drums, and OoV to help with chases.  Blink helps a LOT to get good initiation.

Typical Jungling Build:

Starting: Tango, Stout Shield, Quelling Blade
Early:  Boots, Bottle (or Soul Ring)
Core:  Phase Boots, Blink Dagger, Orb of Venom, Drums
Core Ext:  Basher, BKB
Lategame: Abyssal, AC, Boots of Travel (BoT), Heart

Support LC Item Build:

As a support, LC could level Overwhelming Odds and Press the Attack, giving high amounts of healing and buffing to a carry (creating a pseudo-Alchemist).  However, she needs SOME farm to be effective, and thus should be played as a position 3 or 4.
Skipping Duel at Level 6 would be a good idea in this case, because LC will be under-farmed to win duels (unless hunting enemy solo supports or initiating).  Can transition into a semi-carry late game.

Starting:  Courier, Tango, Clarity, Healing Potion, 3 Branches
Early:  Boots, Stick, Basilius, TP
Core:  Power Treads, Vlad's, Eul's, TP
Situational:  Pipe, Gem, Blink Dagger, Halberd
Long Game?  AC, Scythe, BKB, Boots of Travel
