Guild Wars 2

we got some thoughts about the WvW achievements in guild and searched the most ridiculous achievement in the game. we found it

the Stonemist defender achievement.
in it you have to deff Stonemist 500,000 times!
so the event lasts for 3 mins which will lead us to a play time of 25,000 hours whats around 1041~ days playtime. nearly 3 years. this achievement is a life time achievement. this are 56 achievement points. oh at not to forget after you finish this you have at least 2 chars on max rank in wvw, so no need to do the wvw ranks account bound

for comparison the drinking achievement (where the most people on pve forums are discussing about)
you need 100000 drinks and when you use a karma drink in some outpost which gives you 4 points in it and a doubleclick needs at least 1 sec you need “only” 7 hours to complete it. you get for this 36 achievement points

Lets get to spvp:
to achieve the Legendary Champion you need 14,973,500 rank points.
i think a really good player can do 400 points in a tournament round which will take 15 mins all in all (queue, getting ready, fight) so you would take 37434 rounds and 9358.5 hours. which are 390 days. wiki says for all spvp achievements you get over 1000 achievement points.

so have fun farming
