There's 1-3 weapons, 6 armour slots, 7-9 sockets, and 5 trinket slots. For my class that comes to over 30G on the trading post even if you're running with a single weapon. Obviously that's doable, it might even take less than a week if you're a knowable player with free time, however we can all agree that it's not a trivial amount to spend, and it's not consistent with what ArenaNet have been saying over the past few years in regards to end game.
Im sorry but It is very very easy to get the level 80 craftable sets. Half of you whining are just doing it wrong and blaming the game; It is about getting cosmetics; I hit 80 within the first 4 days of launch and had an exotic weapon and 3/6 armor that same day now i spend my time working for stuff that looks good. Seriously the amount of QQ over any sort of effort on these forums is absolutely shocking.
