I agree with you there, Alyta. Hephaestus was actually a half-decent dude and had to put up with being tossed off of mount Olympus to become crippled, Aphrodite sleeping with other men behind his back, et cetera.
And what was so good about Eris, anyway? She was the discord in battle. The confusion that overcomes you when you're amidst allies and enemies alike clashing all around you, making it hard to rely on your senses. Nothing really fun there.
Now, Nemesis, on the other hand... There's a goddess with a good all-the-time job. XD
