Yes, we, including Guillaume, have read these before. Your link to Eldin's answer is just one interpretation, as are all the others. No idea where you get the "but shouldn't" from: that sounds like your interpretation.
I took the words from sann0638 : "I'm taking vampires this weekend and won't be trying to gaze from prone. Nor will I be rolling to block with a fanatic before doing the required GFI, but both are the case by the letter of the law." + "Time for a new rulebook..."
And here, I would say that we are all in interpretation. so, yes, that's mine. And what I understand in these words is "that's what's written, not wanted".
Regarding the take root, I never heard anyone saying that he can roll the take root dice then decide if he will or not get up the treeman... But indeed, according to the rules, I understand the way you see it.
IMO, that's definitely not the spirit of the rule, which is for me : you declare the action, then you do it. The consequence of doing the action is "immediatly roll the take root". If you don't do anything, then you don't have to test the take root. So, if you test TR, it means you do something, even if it's just trying to get up.
Things are a bit different for HG, nothing force you to roll anything before using HG. BUT, my
logic tells me that the player must not be prone to use it. Yeah, Interpretation again, I know
Well, regarding HG, as said previously (and as you Dode said too), that's question of interpretation. Mine is "player must be on his feet to use it". I am ok if you think that's not exactly what's written (again question of prevalence of the page A against page B). but as a player, I won't use it ^^
Regarding the game, it's up to Guillaume (and also you in any way I guess) to decide. Just wanted to raise the opinion of the president of the NAF on this subject.
@Darkson : I said made, not declare. I know I am not that good in English but as fara as I can, I try to take care
