On my main/first account since I have one character 100 or higher level, I get bonus XP. And I used the 110 class level up token on one other account, so the other character will get that bonus as well.
Accounts with characters at max adventure level get veteran adventure bonus XP for other characters on that account. Accounts with characters at max crafting level get veteran crafting XP for other characters on that account. An important note about that is that the new expansion will change the max levels for both, so you will no longer get that veteran bonus XP until you reach the new max level.
