What is wrong with Foxwoods/Mohegan Sun?

The rules seem reasonable: 0.42% house advantage.

Pen is not terrible: 75%.

Are 8 decks that horrible?

Is there any heat? (I've never felt any)

Now, if you tell me it's always crowded and it's very boring playing 8 decks, I'll understand. But help me out, I feel like I'm missing out on the joke because I don't see what's so bad about Foxwoods.

Thanks
