Tales of Adventure Questions

[Perogwin]

So I am thinking about using these on an alt(s), but I find a lot of the wording confusing.

1. It says that only 1 can be bought per service account, have they said if that will change in the future? I have 3 alts I would like to use it for, I can understand one per character, but one per account seems unfair.

which leads me to

2. Does that mean I can get both a "One Heroes Journey" and a "Scenario Skip" for my account or is it only 1 or the other?

3. If I wanted to use the 2 different scenarios on 2 different characters. meaning put one Alt to the end of HW and another to the end of ARR, will that work, or does that go back to question 1 about having to wait for them to start allowing multiple per service account?
