Another thing I've found is that some people just aren't prepared for dealing with plain, simple, good old aggression.Honestly, with the right tactics - the kind Sir Ganksalot teaches, for example - and just enough engineering to keep your shields from absolutely collapsing in a strong breeze - it's not that hard to get away from a gank.
But most people fly directly away from us, allowing us to easily line up our shots and rams.
Without meaning to sound like a jerk, this is a skill-based videogame, and there are skills that anyone can master to give them the confidence to survive and thrive in Open.
I've sent people packing that strictly speaking should have been more than a match for me just by being horribly, relentlessly, aggressive. People don't seem to expect the little PvE build to boost directly at their face and empty their entire WEP capacitor at them, detarget them when they pop chaff, and keep hounding them. Inexperienced gankers/PvPers get caught off guard when their target fights back - one guy actually apologised in chat as he charged his drives without even firing a shot: I was in my shieldless DBS in Sol going to check out the voyager probes and tourist beacons when he pulled me, and was not ready for me to immediately turn around and unload my cytos in his face.
If nothing else, unless you're looking to gain distance for a low-wake, sticking as close to their engines as you can will make it a pain for them to shoot you while you wait for your FSD to cool down.
