Seeing as cleric has 2 separate personal buff procs and a smite damage proc, has two separate procs they can get from their summon weapon and mini smite buff, I don't think clerics should get anything that improves their procs.
In ONE weapon skill attack today the weapon skill procced itself, smite procced twice for 160 damage, the hammer procced, and the smite buff procced. It was a total of like 184 damage - at level 4. The weapon attack also has 0 damage variance and also hits for maximum damage while my beastmaster can hit anywhere from 1 to 10 at level 4.
I'm sure the damage levels off at some point, but itll be a long time before my best will come anywhere CLOSE to that kind of damage. IMO almost everything cleric has proc-wise needs to be reduced to 25%-40% of the effect.
