Two Weapon Masters in Orgrimmar and only One sells fists?

[Rodgers]

I missed fists because i walked in, saw Weapon Master" saw his offering but no fists. I went into an ICC dungeon and missed out on needing 2 fist drops until someone said "yeah, it's stupid, theres two of them" I couldn't believe it when I got there.

Anyone know why Blizzard did this? I'm assuming there was a purpose besides being deceptively confusing.

One is an Orc weapon-master. The other is a Troll. Each race specializes in a different set of weapons.
