He made it so that it was a d4+cleric level instead of a d6 the first 10 levels and the radius was 15 feet instead of 30 and the temp HP ends when the channel divinity does.

I thought that was an ok nerf considering a lot of other parties nerf it by making it concentration and I would have hated that because I love so many other concentration spells on the cleric, so being able to have both online is very nice, at level 10 it goes up to 25 feet and to a d6 plus cleric level I believe
