Again wrong.
Firstly, this thread is about healing so hit points is directly related to the topic.
Secondly, I am distinctly aware of which mechanics appear bare-faced by some players, I suspect in the instance with HD it is primarily due to their "newness". In my table's own game we have tied HD to more than just reserves for hit points but also to the refresh rates of abilities, the casting of rituals and the exhaustion track. Thus we are treating HD as a proper reserve mechanic.
Thirdly, you have no decent argument against what I'm saying but to keep smearing people as you have done in a follow-up post.
