I do solo build. And to me, it's great
I do +10 STR and go full end after that. I don't really recommend putting a lot of points in STR since it doesn't really help significantly in you damage unless you add about 25+ points in it, but which would cost u 25 levels. Just go light on STR and full on END.
END is really important since as a cleric, you're supposed to heal others too. Won't help if you can't survive a few hits by mobs. If you wanna see more info, like blahs said, look through the cleric section.
