I accidentally discovered this today while helping a friend, he is gearing up but he can't get invited to Heroic Nya'lotha runs, because he doesn't have the Ahead of the Curve achivement and the leader usually asks everyone to link the achievement.

Lets say your name is Faerie (random example) and you don't have Curve. Ask a friend (who has the Curve achievement) to create a lvl 1 char with almost the same name as you, like "Faerķe" or "Faerģe". Then he just needs to link you the achivement, and it will show "Achievement earned by Faerķe". Most of the times, they won't even notice the difference in the name and will invite you to the group, since you have "curve".
