And tons of MMOs have people with the third-best equipment and several weeks of practice (remember those beta phases?) all at the level cap right when the game comes out. Right?
And yeah, most MMOs do have their endgame cleared within a week of it being released. Heck it's weird when it takes more than three or four days, and that's including leveling up and gearing up.
Look, I get you just started and so far nothing's been vaguely challenging. That's normal. Everything below 50 is pretty mind-numbingly easy. The people saying they've cleared Ifrit or Garuda like it's endgame content are in for a surprise when they realize that those are the first 2 of 8 bits of endgame dungeons. Castrum, Praetorium, Wanderer's and Amdapor are not really endgame.
