What I've found however is that invading at these low level you don't run into low level players starting out. Over the last 40 or so invasions I've ran into maybe 2 players that had starting gear, and I'm pretty sure they had just bought the game because they didn't know how to use lock on.
Most of the players I ran into were gravelords with lightning katana's or lightning bandits knives.
I've ran into guys who camp out by the bonfire and jumped me with twop and wog.
A few players were farming with their sunbro's.
Even when I used my claws at +5 lightning I couldn't touch half the guys that I invaded here.
One guy was just chilling out with full giants, mask of father and a fire/chaos estoc.
All in all my opinion on griefing has changed. It doesn't hurt low level players. Out of 40 invasions I saw maybe two players who were legitimately new.
