Bless effects can't be judged.
It all depends on what unit is to be blessed.

A water bless for Nifel giants is ok. But they will fatigue faster and actually be less effective in larger battles where an earth and or nature bless is much more effective.

On the other hand a water bless is superb for a unit like EA TC's sacreds when an earth and or nature bless is not as good for this unit.
