I disagree though. People didn't farm PK EP because they didn't know the actual accrual system beyond PKs= EP, they had no idea about level based and such. Engaging in PK wasn't a farming behavior by the PB initially, it was just an accrued ancillary benefit that came from PKing.

Only once the system was known did people people attempt to farm it, as they would have no matter what obs/explore yielded in terms of EP (unless it awarded so many you could take every available edge)

You can't actually believe players would ever think they have enough edges to the point they wouldn't farm EP reward systems if they were able to and knew how. Some wouldn't, but the min/max style definitely would (it's an advantage, or it's greater customization, or whatever reason they choose to). If they can amass 5 more edges by engaging in behavior X with no downside, they're engaging in behavior X.

There's no such thing as "enough" edges to a player. I had 28 edges on Salyeris and 26 on Allysia, and if I did a discuss and could take another edge I thought might be useful on either of them I would have. I didn't say that's enough, I'm not taking any more edges even though I am able to. And I doubt any single player would say they wouldn't either. They might save for a more expensive edge, but they're not forgoing selecting another edge altogether after some point.

Twist fostered (inadvertently perhaps) PK farming with his detailing of the system. It's difficult to argue that wasn't a result which led to the necessity of altering (or in this case nuking) the PK EP system.

All heroes farm PKs, that's sort of what you do in CF, since PK is a big part of the game. But prior to Twist, people were not as often sitting at set level tiers trying to amass PKs because of the bonus EP it conferred, multi killing or otherwise in engaging in behavior they otherwise would not but for the sake of the EP benefit. Players, by their own admission, have compulsions to try to maximize these things far too often.

The only way your idea would make sense was if there were so few edges available that a player could run out of edges to take, so there was no bonus to farming because you'd end up in the same place. But even then people likely would, because they'd want to accrue those benefits as early as possible.

And as it stands, most characters have a minimum of maybe 35-40 edges they can choose from.

EP transparency was clamored for, but the end result once it was given was nothing but players looking for ways to maximize the system.

Too much transparency into edges probably did more harm to the system then anything else.
