Uh? This is dumb. I'm using the term to refer to a behaviour that I think is particularly dickish and clearly defining this behaviour. I never said that all low-level invasions were lame (some can be fun and exciting), that was just your giant pile of straw. When I patiently clarify what is the behaviour I consider dickish and why, now I'm "changing the definition"? *shakes head*
Exactly.
Eh, Demon's Souls has no weapon that OHKOs without a backstab unless you're facing someone with really pathetically low VIT... Especially without a buff.
Griefing IS "dickish", and it's enjoyable and built into the context of the game. Case closed.
