Just a follow up and to answer some questions.
- No, there was nothing laggy about the encounter, all motion was fluid, no stuttering or jumping.
- No, he didnt fire off any SCBs, he didnt have any equipped, just shield boosters, lasers and plasma accelerators
- I sincerely doubt it was a random glitch due to his behaviour. Not only did he enter PVP combat without a single SCB, but when his shields went down (pretty fast I might add, he really wasnt trying very hard), he didnt run, didnt try to shake me off, didnt boost away or try to get behind me, he just sat there lasering and plasma'ing away. Thinking back, Im half wondering if he was somehow manipulating his WEP capacitor too, it was non stop beams and plasma.
Ive been hanging around the same few systems for a few days keeping an eye out for him, no luck so far, but Ive got some screen capture and rewind software installed now in case he does show up.
