Yeah, I was going to mention the Sheshai Anakites since they also have half the resource cost. Usually gold will be the limiting factor here but resources could sometimes come into play.

The only thing is, with 14 prot they will likely take some damage and go berserk even with an E9 bless so you may end up with a similar fatigue situation as with the nonberserking Ahiman Anakites. But if you can reach Alt. 3 for BE you could delay them going berserk.

But I think rdonj is right in that you have to look at other options in your lineup or even indie units like archers. In this case I think ghoul was facing a 3 vs 1 so he may not have had the gold to switch up his troop composition much anymore but generally speaking you have to tailor your approach to the opponent and can't rely on one unit to handle all situations (if a unit can do that it's almost a sure sign that it's OP).
