How many times haven't I got happy, proud whispers from friends sending over the Recount charts after a PUG, showing that they did twice as much damage as anyone else? People love to excel, no matter if it's out of gear or knowledge and dedication to the game. I have yet to hear someone complain "damned, I topped the meters again, I've been used once again and tricked into boosting the other M&S for free"."
Well, you are haring me complaining about it all the time. Everything I do, I do for a purpose. I expect a gain from the activity, either material reward or "self improvement". Overcoming a challenge makes me a more effective person, gaining stuff give me the tools to overcome challenges.
The challenge comes from the environment. I don't really care (or even notice) that the same challenge is defeated by others or not. It's just me and the hill. If I can climb it, I'm satisfied, if I fail, I'm frustrated. I completely ignore the other climbers.
I've noticed that most people are not like me. However I never thought that their different thinking is more than something funny. I see that people want to "win", want to be on the top, even if no reward is given for it. I simply considered them silly. However you are right. Many can be motivated (at least sub-consciously) to boost M&S in order to feel "winner." While most of the material gain from the raid go to the others, he feels that he gained something important, maybe "respect" or "status". Of course the mentioned "resources" are not measurable, un-scientific, non-existent things.
I was annoyed every time when I outhealed others by a significant margin. I pulled more weight than them yet they got most of the rewards.
In the ape-horde the "winner" was the alpha male, with exclusive right to mate with the females. The subroutines are still in our head, giving good feeling when we win over others (as opposed to against the environment). The word "e-peen" refer to this, mentioning that the winner somehow will be more successful in sex.
We are not in an ape-horde anymore. No one will have a date because he topped the DPS meter. Actually the image of a video gamer is everything but "successful in dating".
Granted, material wealth attract a kind of women, though I have serious doubts that that kind worth attracting. But material wealth comes from reward oriented thinking and not by "winning".
If you are in top of the DPS/healing meter you are used. You pull weight for others. You may feel being a winner, but actually you are just a workhorse. You work, they loot.
If you want financial freedom in the game and in life, you have to do things that bring you material rewards. If you are seduced from such activities by ape-subroutines, you may top the DPS chart on Malygos or have 4 touchdowns in Polk High, but that does not save you from the shoe shop with many fat women. Think about that.
