What is so technical about it? What is so complicated about it? And what is the difference on freedom and that component of deaths advance? Both prevent moving impairing abilities, it functions the same? If not, explain the difference.
Its bit ironic because you seem to lack basic understanding of what the fuck you're talking about but trying to hide behind "ohh, its so complicated and technical", like no, no it isn't.
If you can't explain it yourself to others? you dont understand it yourself.

Its a change to how the game works, its not a ret/prot thing, its a dps vs tank thing.
