What are you crying about?
From reading your jargon all over the place, where-ever you happen to post, any gear change for you would be "gear tax".
1. Nope.
https://www.youtube.com/watch?v=LByxE48-ATk Or define your meaning of dead slots? Specifically to the mid-end part of that video he explains how tier along with a couple of other systems made gearing far more interesting and something to care about. And now that I think of it, by your whatever you mean by dead slots. For me personally, all the slots of gear except the trinkets are dead, because I don't give a flying F about any of them, and haven't for an expansion or 2 now. I only know the name of the vita trinket. Szhkuul Vaz or whatever it was, I don't remember anything else off the top of my head, having given it a solid minute to think of. N'zoth shoulder piece vaguely resembles a name.
2. Just like losing everything else will get you pissed, especially the 40% haste going away from hurrdurr corruption, this argument makes no sense.
