Enchancement: Frostmane Seer unknown language

[GarzorTV]

First of all: this is not a bug but maybe an enchancement for the game. Just pointing this 1 out.

The Frostmane Seer troll mobs talk unknown language for Horde. (See screenshot for info.)

Original Frostmane Tribe language: Main language : Zandali, Low Common, Common (Should be viable to Horde)
