Well, since so far we only know that Player's Handbook subclasses will be added ...
Shouldnt that list be a little shorter?
Namely:
Knowledge
Life - in game
Light - in game
Nature
Tempest
Trickery - in game
War
//Edit:
I will say that the cleric in my tabletop game dishes out Lesser Restoration pretty often but I’ve never needed to use it in BG3. Is anyone getting any mileage out of it?
Oh yes ...
You can help
Pandirna with her legs problem ...
You can help that gnome in Myconid village (she dont have entry on wiki ... and i dont remember her name) ...
And i believe it can become quite usefull in fight against spectator.

And acording to
this topic on reddit ... it sounds like usefull spell against Hag aswell.
