I am esl as well. I don't have much exp for my roles. Now I don't get pk edges for pk kills as well. But its fine. There were the clown (clowns) who spam killed newbies for edge points, over and over again. The old system encouraged to harvest kills on low levels - now its fine ( and still I would prefer to make it like the ap-system with charges. )

You get edge points for lots of things - rank to hero, second name, reraids. Its more then enough. Nobody needs chars with billion edges on low levels that make them even more stronger just because they spam killed noobs and saced their pies.

PS: Just make the search, you'll find old threads about that. It was 1-3 months ago.
