Yes, I agree with thejeff. There is not much need for the sacred. They hardly bring anything that chariot and dawn guards don't bring, even with substantial bless. The only case you might want the sacred is when you face super blessed F9 troops. Also each rephaite warrior devour as much population as a ba'al. (source:dom3db). This, my friend, is really bad.

However, I do find the single path mages somewhat lacking in the mid and maybe late game. You cannot forge most useful stuff, and level 2 is not really that great for many single path spells.

Also they are easy to lose focus. If you go blood, you probably will lose the artifacts war. On the other hand, you need evo to help your troops, thu and conj to site search, alt for useful spells for your SCs. The choice are many and hard. It would be challenging to play them well.
