* Lucky Shot can disarm Legion Commander and reduce her armor, which can reduce her chances of winning a duel. If an ally is targeted, Pangolier can simply use Swashbuckle to inflict it on her.
* If an enemy Pangolier casts a well-timed Rolling Thunder before Legion Commander can cast Duel, it might result in her chasing down Pangolier until his or her ultimate ends, whichever duration ends first, resulting in an open window for enemy allies to target Legion Commander, making her vulnerable and susceptible to any source of attacks. If Legion Commander has an Aghanim's Scepter in her inventory, the risk of wasting a solid 8 seconds would result in a futile duel.

* With too many clone running around during combat, it is almost impossible for Meepo to avoid Rolling Thunder or Swashbuckle.
* Still, remember that a lone Pangolier can never escape from a ganking Meepo.
Additional:

* Spirit Breaker's slow attacks cannot harm a hero shielded by Living Armor.
