Einherjar lockout time

Is there anyway this can be shortened as it's a huge bottleneck for people making mythics and also could the text be changed? we know it's a 1 hour lockout per run but the text will always say "Entry to the chambers is prohibited for 1 more Vana'dielian day." even if you only need to wait 5 more seconds. maybe have it changed to for example "Entry to the chambers is prohibited for 45 minutes."

I'm not sure how this is a bottleneck for you. I've made 3 mythics now and i've never run into that issue. If all you do is one part at a time yes you will run into this. Usually i do all the missions, then between Salvage runs or Nyzul i will do Einherjar. Just keep an eye on your one hour timer.
