How do you want to earn Achievement Points?
No, no and no. I think we have enough infinite achievement earning ways (daily, monthly). That 2 are more than enough, no need other ways. That is only point, nothing it profit. In GW1 the GWAMM was great that was a good profit for play and doing titles.
In GW2 yet useless. The very first thing is good in Achievement Points the Living Story (exotic gloves). we don’t know what the future brings, but we feel we need changes around the Achievement points.
Achievement vendors, valuable reward etc.
In the Defiance sci-fi MMO the achievements point (EGO Rating) are integral part for the game and the rewards are kitten good (Costumes, Mounts and other cool things).
If in GW2 would be kitten good rewards too for achievements points, then would be good idea your suggestion. But now this idea is useless like the achievement points too.
At current, achievement points are displayed on the party interface when you’re in a party or just in your guild window. They are a great indicator of which players are more experienced than others and if any people are fairly new to the game and may need more of a helping hand.
This is helpful in not only leading successful groups and guilds, but also being a helpful team member of a group or guild.
