We will have to wait and see if they scale damage or not. Also, you 'could' cover with shield oath on, but that means you are main tanking and using cover.....unlikely, or you wasted 2 gcds to turn it on as an OT. Also silly. "Pld can turn on tank stance for 40% and now it's only 20%" is a BIG stretch to make updated cover seem worse than it is.

Cover is fundamentally the same as before in effect. All that's changed is it isnt free. So yes, there are times that cover would be used if it was free that wont be worth it anymore. The effect is as powerful as always, it just has a cost to reflect that power now, so it will be used less, but as long as it cheeses mechanics, saves people in trouble, prevents swaps, knockbacks, debuffs, etc it will find uses. Just not as many as the use must trump the >0 cost.
