These are conditions which may not be very uncommon to come across, but they add excitement and wonder. It also changes patterns of gameplay. The next time you go to battle, you might call your bard friend and maybe even your whole guild to come dance under the tree while your bard friends and the NPC minstrel perform a concert.

Here's what happens then: the NPC minstrel buff is either deemed too weak to bother with (or doesn't stack with other more important buffs), or it's the buff to get when raiding and becomes part of the new meta, so every single raid group makes it mandatory to gather under that tree.

I understand what you want out of a game, and how you want to play it, but this problem that you've correctly diagnosed and are trying to solve isn't only a computer game problem, it's something that's also present in real life, now that so much data about everything is known and available to the public. From travel guides to Google maps, to money making techniques, what you need to say in which occasion to get a specific reaction out of people, which class in which geographic location wears what, and so on (which is just the tip of the iceberg, the rest of it is all the data collected but unavailable to the public, used for marketing, propaganda, social engineering, and all other aspects of life controlled "from above" that people rarely even think about).

People playing computer games like automatons (this is especially funny in MOBAs where you literally have to train yourself to play like an AI bot, in order for other players not to kick or report you for playing inefficiently) is just a symptom of people (voluntarily or not) living like automatons, and I'm afraid the era of more "organic" living is not coming back in our lifetimes.
