Sorry for late response but think about DB/PA power restore as an icpr, I can hit DB/PA almost every 4/5 sec, if it crits lets say every time so I get 209 power every 4/5 sec, its almost 2400 icpr, thats not including power restore from defensive strike, and plus I get like additional 100-150 power from traited rallying cry. Even if it crits every second time than its 1200 icpr which is still significant. I hope those rough numbers makes sense. And also I have cry power cost and melee skills power cost legacies maxed out on my weapon. If u want real numbers I can run my combat analysis.
