Hi,
I reported the bug regarding the refund of Energy on Dodged / Missed specials during beta, and at that time I used as a main source the same website you've linked.
I used the article linked in the article you've linked,
Energy Regeneration Oddities, in which the author explains Dodged and Missed combo-awarding abilities only cost a fraction of their energy cost.
The author didn't say a word about Parried attacks in this article, and since it was from 2006 while the one you linked was from BC, Parries were kinda left behind. To be honest I checked a few videos too to see misses / dodge, but failed to see any Paries so since it wasn't 100% sure only Misses & Dodges were scripted.
The authors did his tests on Kurinaxx in AQ20, which could explain why he didn't get any Parry (i.e. no Parry from behind but still Dodges) and didn't mention it in his first article.
Nonetheless, maybe the staff would like another proof like an actual footage, or maybe another post confirming that nothing changed regarding Energy refund on Parries between Vanilla & BC, something else that could counteract the fact that nothing about Parry is said prior to BC.
