First of all, I'm not a pker, I've almost never PvPed in Runescape. (And when I did PK, I sucked ass.)
So what I've gathered from all of this is that you should get some kind of safety bubble protecting you from pkers while you kill your bosses or that you could do your clue scrolls and diaries in peace.
The whole reason they added bosses, skilling content, resource area, diaries etc. into the wilderness was to give it more action and a reason for pkers, pvmers and skillers to go deeper into the wilderness. High risk, high reward.
You complain that you are forced to go there with your ironman, complete clue scrolls and diaries.
You chose to limit yourself making an ironman, stop complaining. Still, you are not forced to go there.
You can 3-item every single hard & elite clue step in Wilderness which means that if you die, you won't lose anything so I don't understand why are you complaining about this. You are not forced to the Wilderness and complete the step, get another clue.
Diaries, seriously? All of the steps pretty much requires you to go to the Wilderness and all of the rewards are based on you going to the Wilderness. What forces you to go there and complete Wilderness diaries?
You complain about charging glories and then someone coming to spear, teleblock & kill you when you can charge your glories in Heroes' Guild. Or you can, you know, bring 3 glories at a time.
You complain about people ganging on PvMers? And? Clans have pretty much always ganged up on a smaller team or a solo Pker, why should PvMers get away of being Pked by a team?
Jeez dude. It's the wilderness. The whole reason of wilderness pretty much was and still is to PK other people.
