For advanced pvp player 1VS1 is sacred ! Even with unbalances between class. It's a civilized art and an encounter between two respectable players. The result is less important than the fight in himself. If you almost kill a summoner with your bard you still can be very proud of this by exemple. If you kill him alone it means this summoner didn't very well know how to play so you didn't feel really satisfied with this fight. That's how you feel when you got the true pvp spirit !

Some get it, some just feel strong by "banging" a poor lonesome man.
