Woot! As of I8, Titles on characters (“The Valiant Victorious Torchielle”) will be much more malleable.
You can change your title at any of the following levels:
15, 25, 35, and 45
At 50 you can change your title at any time.
You need to visit a trainer still to change your title and they “don’t stack” (in other words, if you don’t use your level 35 change, you don’t have two changes when you hit level 45).
There is no Influence or Infamy cost associated with this.
Joined with the previously mentioned expanded title list, this is fine news, and makes great sense (though I would have accepted a bit of Influence/Infamy as a reasonable cost for this, if you think about it).
Now … when will they let heroes/villains start to self-service change their names?
