It's pretty much the exact same before they reduced the activation of EPtS from 30 seconds to 20 seconds.
You got your 100% uptime back. Not sure why people are still complaining about it.
From my understanding, unless something has changed, the uptime has been reduced to 20 seconds yes, but the recharge time is longer leaving a gap. The gap becomes even more pronounced when you try to cycle two different eptx abilities such as in the dragon build.
