Sicne the introduction of the achievementsystem in WoW, I have been rampantly against it. I find no enjoyment in fulfilling random tasks to be awarded points, which in turn can only be used on vanity things such as titles or mounts.
Its just not my cup of tea.
If we have an instance on farm, I much rather just farm it quickly - so I can return to doing something else. Like making money, lvling alts or grooming my giraffe. Making encounters unnecessary difficult (by f.ex. not killing the adds) just dont sit right with me.
Now it turns out I kinda have to care.
When ranking guilds achievements are counted. Sites such as http://wow.guildprogress.com/ will rate guilds with more achievements higher then those without. Regardless of who first got the kill.
So, to achieve our goal of beeing a top guild on the server - we need to complete achievements.
Just like that - a ranking system that I do care about, forces me to care about achievements - a system I dont care about...
