Actually, Umbreon's a decent supporting wall, and it has an actual attacking move that doesn't rely on its own stats (Foul Play).
No such luck with Flareon, however. If only GF could give it better physical STAB moves than Fire Fang... --- "Many of you feel bad for this lamp...That is because you're crazy. It has no feelings! And the new one is much better." (IKEA's Lamp commercial)
