i've only lost to a rogue once.
and it's because i was already injured from killing a dk.
the only ones really capable of killing a warlock are a paladin (stupid infinite life) and a frost mage (freezing + critical frostbolt)

WHA? YOUR WARRIOR LOST TO A ROGUE?????
you really really should be ashamed, as geo says.
it's like having an iron sword and iron armor and losing to a guy with a copper sword and leather armor :/
wait - worst
there's a lot of noobs trying to act cool using warlocks and they're just bringing shame to the class.
i've seen them... they think warlocks are used like mages LOOOOL
/facepalm
