...Or the Hand of Vengeance & the Taunka.

Agreed. Where are the commendations for the rep that are HARD to get? Frostborn, Explorer's League, no doubt the Horde equivalents... even the Kalu'ak are harder, with three dailies in three different zones, than any of the factions that can be championed and have several dailies of their own.

I don't get the complaining about the Sons of Hodir either. Some of their quests were annoying, but OK, then, just don't do those. As rep grinds go, there are a lot that were harder. Ogri'la took longer, SSO might have been quicker but its quests were spread out all over Quel'Danas AND Outland, and you couldn't start Netherwing until you did a five-man quest without the help of people who had done it before.

I am exalted with Frostborn and Explorers league, after having killed a billion drakes on my eagle, and shot down so many gargoyles I suspect they will go extinct. The reward for which was:

a) Eagle mount!
b) Cool tabards
c) Pets
d) Achievement
e) A mild tingling sensation I wasted 6 months for zero rewards other than a rep bar

On a related note, I agree with Cyrus however: People who consider the Sons of Hodir a "tough rep grind" have not apparently completed any "actual tough rep grinds".

What are you talking about? There's no reward from getting exalted with those factions that I know of, and I can't find any kind of an eagle mount anywhere on wowhead.com. Unless you just mean the one that's provided for the Frostborn daily, but (a) you don't get to keep it and it doesn't count as a mount, and (b) that's available at neutral or friendly.

@Cyrus

Ah, that was intended as a sarcastic multiple choice; my point was I got nothing (e). Unless they alter that I see little point in adding commendation badges for those factions at all.
