Ascendancy and passive tree

I know many disagree with this but I think Ascendancy and the whole passive tree needs the possibility to a hard reset.
the good thing is poe is to explore possibilities, and you can achieve that with the freedom to try various builds, but the refound passive system right now is lacking a good hard reset button, i'm fine it even cost some currencies instead of gold.
And ascendancy really need the possibility to be switched, right now the only thing you can do is roll 2 character per class which is not optimal, with the chance to hard reset it and change your path you could be able to explore the depths of this game.
And we need a training dummy with dps meter to try out our build, maybe a separate map where refound is free so we can swap and try as many time we want.
