my opinion has always been the same, protect everyone or no one, simply keep it fair, i havent changed this position.
as for lvl 20 getting protection to hunt, im sure lower lvls would like to do chaos rep on faygo with protection too, but its a war game so they dont, im sure lvl 11+ would like protection in mage lands, but they dont get it.
and its not just a attack rule, it als protects from negative effects (which players can actually protect themselves from, and even being stalled, since when did ppl ever have protection from negatives and ppl stalling them, its a rule designed by a few to protect the few, my point stands, rules should protect everyone equally, anyhing else is a travisty of fairness, and shows only bias owards some
to clarify actually, lvl 11-15 have protection by staying in eldive/kroff lands. You would want specifically the white castle area to be treated like ruins for lvl 11-15 to have full protection as well.
My two cents on the whole thing is the attack rule was a means to stop low lvls rage quitting because people were getting executed for a lot of things. Ruining gbs as a low lvl was one (I know I executed low lvls who jumped in gbs on plat and pretty much screwed the wins), but then the more petty ones became about fighting for rare resources, and then of course exe orders from someone who is probably pissed at you and then you got whacked across the head by some high lvl with lvl 300+ exe.
When attack rules came in, people felt more bold, and by being more emboldened, they started to do what they please. Khan put it really nicely about what the game is about, which is progression, and that's the ultimate goal for everyone technically speaking, but like every rpg or mmorpg, you can play it however you please, just don't make other people feel miserable for your own means to an end every single time, because that means you're the problem, not them. At least there's a clause that if a low lvl provokes a higher lvl and gets a hit, we have to justify the reason with a screenshot, but then it's up to personal definition of what is a provocation from every guard.
But to also look the other way, you'd either just remove attack rule completely and we'd go back to 2015, or have the attack rule apply to everyone, which means more random whacking, but at least it helps everyone keep a slight civil tongue on themselves with a clause that means that everyone has to be civil to each other.
