Translated - you don't have an answer for it, because you either ignorant on the matter or simply want to stand there with your fingers in your ears stamping your feet.
Anyway, time for some education, this is what Colin Johanson (he is the lead dev for the content team) stated on the Arenanet blog before release:
"We don’t need to make mandatory gear treadmills, we make all of it optional, so those who find it fun to chase this prestigious gear can do so,
but those who don’t are just as powerful and get to have fun too."

This and similar messages were repeated in many interviews, videos, Q&A sessions & in their manifesto pre-release, by multiple high ranking Anet personel (including co-founders/game director), I am sure you can find the thread in the GW2 general discussion forum for more, they sold a game on one premise and 3 months in have done a u-turn.
Sure it does I've won & lost encounters by sometimes tiny margins (under 100 HP even), the difference is only going to get worse as they add higher levels of infusions and ascended items to more slots, that was not the game sold to me by the frankly dishonest Arenanet / NCSoft.
