When you have lots of XP, it's not actually worth the time it takes to run into Central Brit for the 8000 XP for seasonal enemies. Some might say "Well we don't want that, kill him for the sheer fun of it!" And we did. But XP is nice too, for both the game and the players. In fact, 8000 Xp is a letdown at higher levels, you're better off not giving any as 8,000 has become a running joke.
