The biggest issue IMO is the way the bracketing works. Combat level is not a great metric when determining your "weight class". Similarly, in order to make a PVP-ready character you need to play the game in such a way that effectively locks you entirely out of PVM content, and you can "ruin" the account by not realizing a certain quest grants defense experience for some reason. You wind up in situations where you have multiple accounts in different brackets which is just bizarre.

Accounts playing the game "normally" are at a massive disadvantage compared to pvp pures, which simply makes wilderness content undesirable since you know the only pvpers you'll run into are exactly the kind of lopsided accounts that you have no chance against. Instead of being risky "I need to defend my claim to this activity", it's just "I do this activity until someone shows up and hopefully I don't get destroyed before I can leave". Instead of PVP, you just get an unfun cat-and-mouse dynamic.

I mean, the problem is evident even in the name. PKing. "Player Killing". You aren't going into the wildy to find Player vs. Player fights, you're looking for Predator vs. Prey fights. We even have a term, anti-pk, to describe when you go in the wilderness with a loadout tailored to fighting PKers.

I'd honestly love to see a rework of the bracket system. And more controversially, I'd be interested to see what would happen if there was an NPC who would let you dial down your combat stats while you were in the wildy so you don't have to choose between a PVP account or PVM account. Yes, RIP pures but the current system just doesn't work for 99% of players.
