The reason people level sat and multi-killed was because there were EPs available for every 5, 10 & 15 PKs every 9 levels, or so. Plus, there were the general PK tiers on top of it. That was a lot of available EPs.

Under my suggestion, if you want the EPs badly enough it would be much easier to just go out and get the explore exps, especially for the first two tiers (5k & 10K).

However, if you are tired of exploring and just want to be involved in PK, you can get some EPs every so often for it. You just give up the opportunity to earn EPs exploring to do it.

Did I not explain my idea very well in my original post? I feel like people are missing the idea, so maybe I didn't.
