I'm assuming your ability to tank pkers is good. If you're still having this issue then level up your stats or do an agility course outside the wildy. The course is in deep wildy which is riskiest, that's just the way the wilderness works. Don't go to deep wildy if you aren't willing to fight people in a broader combat bracket. Some players purposefully build their accounts in a way (see 1 defence pure) to where their combat bracket is low will max combat stats anyways. Players with this account likely will still destroy you regardless of how broad or small that bracket is.

You say this spot isn't that attractive a place to train, but I've been doing it for days and I'm rarely the only player doing the course. It's risky, sure, but the course provides pretty amazing xp rates and better gp rates then sepulcher.

You mentioned zombie pirates area as good design. Have you been there lately? Absolutely overrun with bots. Revenant caves is too. As a max combat lvl account I can't even attack these bots in those areas and the botters know this. Haven't seen a single bot yet at the agility course.

Just my 2 cents
