I wanted to ask for a clarification on the Mastery Point/Spirit Shard mechanic. I understand that if all Mastery Tracks are completed then any experience gained afterward is shunted to a hidden, invisible track that awards spirit shards for each level. (There is any way to see/monitor this amount?)
What happens if you do not have enough Hero Points to complete a Mastery Track but the Experience Bar for it is full? Is any extra experience you gain being wasted or does it shunt to the hidden Spirit Shard track?
Also out of curiosity, what happens if you just finished a Master Track but you do not click 'Train' on the next one (say because you have no interest in pursuing it)? Is any experience you gain next then wasted or does it go to the mysterious, invisible Spirit Shard track?
And this mechanic is the same for each expansions since the game treats PoF and HoT experience as separate from Central Tyria experience?
