Please allow me to use the sentence I quoted from your post, as this is were I believe you are the most wrong. Let's have a look at the opposite statement:
"Everyone likes being outgeared in structured PVP and winning due to be able to do 30% more damage than the opponents." Since this is reasoning with absolute, it is therefore wrong, but I'm betting it's a lot closer to reality than your statement.
This game is a MMORPG. By definition, you are meant to level up, get stronger, face stronger foes and slaughter countless weaker opponents than yourself. This is the very core of a RPG and what RPG players expects from a RPG game. Being a MMO just means that a lot of other players are progressing in the same world as yourself. Whether you want to stand at the top of these players or not is irrelevant. You want to get stronger and the game will comply to your needs to do so.
I believe that true display of skills is only possible when the odds are stacked against you. If you are absolutely equal to your opponent stat-wise, then you must take into account lag, game bugs, class inequalities, computer power, keyboard speed, random number generator for damage... Both of you may press on your respective keyboard/controller the same key at the exact same time, but end up with one character striking first for maximal critical hit damage, while the other goes second with minimal damage. There is no skill in that. Maybe luck at most. Therefore, your victories might all be considered to be luck-related.
On the other hand, go against a superior force, significantly better geared, while being under-geared and manage to steal the victory, there can't be luck in that. The opponent outgearing you will have an absolute damage output much higher than you and a damage input much lower than you. Winner this battle fairly is therefore only explained by pure skill. The opponent can of course find excuses, but the fact remains that you should have lost and you won. Problem is, not many players are actually skilled or want to spend enough time to reach that level. Therefore, they go for the gear advantage. If they can endure losing long enough, they will get better gear and start winning against weaker opponents.
This is RPG logic. Cover your weaknesses with companions and/or powerful gear and save/conquer the world. Standing on the top doesn't mean to have the best skills, it means a combination of dedication, skill, experience, training and gear to back you up. Again, RPG logic. If it was fair, than young heroes would never thwart a villain's masterplan that took years of efforts, training and preparation to achieve, simply by swinging around the MasterSword. We want to get the MasterSword and kick the villain's ***, in a timely fashion.
Winning is winning and not everyone thinks that a victory is only a real victory if you have out-skilled the opponent. Too easy or not, it is common knowledge that most people will enjoy the victory.
