Q:
Personal story CTMP
Here is what the Wiki states (at top of page):
Note that for the Hero achievements, a mastery point is only awarded the first time a player completes the personal story arc for that level. (Emphasis mine.)
https://wiki.guildwars2.com/wiki/Mastery_point_unlocks
In other words, an account can only acquire 8 Mastery Points through the (Core) Personal Story. One for each Level Arc, regardless of race. This has not been changed since inception, though the Hero Panel (and the Wiki) is confusing, as it lists all possible ways to acquire the 1 Mastery Point per Level Arc.
Good luck.
