I got to play for an extended time this weekend, and almost finished a whole epic game. Which is why I haven't updated the FAQ yet... 
Anyway, I happened to build this wonder for the first time. Pact of Nilhorn. I got a random goody tech, as I never go up this tech branch first.
It's a lot of fun. My vote is for the three giants to be heroes of a sort. Just differentiate them a little from their wild breathren in the unknown hinterlands. Jorgund the wise, Barak the Beast...etc...Remember these are not just the monsters from the hills. These are giants of legend that have come to go war with allies. They are a known to the builders people, and thus should have more personality, flavor. They don't have to be alot stronger, just have some character upgrades. Since they don't really get experience. How about a strength 4 giant, with crazed. Maybe one who's a good rock thrower for the sieges, as aforementioned. Maybe the last one's a shaman with a quirky giant only spell. Could be fun.
