Life is a bunch of choices. Some are under your control, some are not. All choices have consequences and opportunity costs.
A couple of members of my guild at the 10k mark chose to focus on different things: one wanted legendaries- He’s now working on his 19th. One wanted to play GW2: Wall Street- He went from 0 gold 9 months ago to his target of 1 million gold at the beginning of this month.
If you’re not willing to play to achieve a goal you don’t deserve to have it handed to you. I never played GW1: do you think if I complained enough Arenanet will give me those 500 achievement points? If they did, how do you think all those people with the GWAMM title would feel? For that matter, even if I bought all the GW1 games getting those 500 points might be impossible now… but thats life.
When the achievement point reward system was introduced, there was enough information on the wiki to predict that if the pattern continued the remaining 3 pieces of one set would be awarded by the time you hit 29k. Some players decided at that point, (whether to go for that set or to get the account bonuses) to change their play to systematically get achievement points. Those players have been pretty much in lockstep with my own progress on the leaderboards. A few have passed me.
Everybody had access to the same information. Doing different things in this game gives different rewards, the degree of focus determines how much of any given reward you get. Thousands of people made the choice to systematically go for achievement points, and have already paid the opportunity cost to get to where they are. If getting those skins are really personally important, you’ll do the same.
