Some ppl will say that the miracle proc nerf isn't a big deal bc you just take more time activating miracle for the first time and then it's always active anyways, and I agree, but precisely because of that i voted revert the proc chance back, it is almost inconsequential, and it doesn't affect the power level of the class in any way, it's just a small QoL change that was removed.
SE should maybe get their own set of custom nerfs in Purga/Fortessa/GA, but reducing miracle's proc chance really doesn't do a lot considering it las an entire hour and is very likely that it will proc again before the hour is done.
In any case, I agree it shouldn't be lost upon death.
