Ironblood is still fantastic for pvp... major and minor protection at 100% uptime is good. The 25% snare is manageable.
Minor protection is fairly easy to get, and major can be slotted as a passive but you lose a bar space. So ironblood now is more niche, but its still good.
Notable mention for Aetherial Ascension if you can deal with the increased cost.
I'm actually using Aetherial Ascension on my WW build and I've been able to negate the extra drain largely through armor traits and champion point perks. It actually works better than you would think.
