You have a good point, however, i think that the devs has a responsibility to make sure that newer content don't "conflict" with older content and i think the "issue" of Cape of Legends vs. Obsidian Cape is a prime example for gamedesign gone wrong. In regards to the Proselyte vs. the White Knight armor i can now see the question isn't so easily answered as you need higher stats to wear Proselyte than White Knight armor. If they had to consider older pieces of equipment before making new ones, nothing would ever be released. The alternative is to only release new items to people who do all quests, and that would alienate the (notably large) portion of Runescape players who do not like doing quests.
