Leaderboards are useless, it's all dependent on how many dailies you've done instead of actually doing in game achievements. They obviously didn't put much thought into this at all, as always. Around 40-50% of their points will be from grinding dailies since the game came out, meaning it's impossible for new players to make the top list. I never did dailies until laurels came out and I only have 3k achievements, I would never even get the chance and I've been playing since beta. Lol.
Dailies can't have that much to do with it. I've done every daily since the beginning and in some cases multiple times a day (after patch resets) and I only have ~4k achievement points, which is almost half that of the #1 spot.
Well, that's including PvP dailies/monthlies. Scared me for a minute because that'd mean only ~1k of my achievement points were from actually playing the game and I knew it had to be more than that. :P
You really think there's a meaningful comparison in PvP or WvW? Leaderboards almost never are actually meaningful since they assume that if person a has beaten person b and person c has beaten person a, person c would also win from person b.
There really isn't much of a difference between "who has most AP" and "who has most win%"
