This is what makes the allies rules more or less useless, because if you're using the allies to cover your weaknesses, you might as well just be playing that allied army because you already have the models, you already have the book, and they don't have that weakness which you want covered.
Not necessarily. Sometimes a thing is more then the sum of its parts. I think the deathcult, a unit which runs contrary to all the rest of the Sisters units, shows that.
The deathcult ends up being extremely good because it fills a gap in the sisters army. The problem is for practical purposes you can only take one. If instead of getting a death cult we spent those points an dark angels picking terminators now we can have up to three groups of CC specialists with better protection and some shooting ability without giving up the sister's strength such as our powerful Heavy Support slots in the form of exorsists and our powerful HQ choice of Celestine. Further with the terminators helping to protect our Battle Sisters from CC they can actually be more effective now able to move into rapid fire range without worrking about being swept aside into CC.
If I were to just play dark angels I could not do that. I couldn't take celestine and I couldn't benefit from exorsists and that would result in a very different play style with very different strengths and weaknesses. Might it be better to go pure DA? I can't say, but I can say that dark angels play very differently from a SoB+DA alliance army does.
The final point I would leave on is that Sisters of Battle are and have always been designed to be an ally or have an ally to fill out their ranks. Their roster has never been a complete one so, even your assertion about allies is true for every other army out there the Sisters are still an exception, an army meant to act with another army to make a stronger whole, by design. If we assume the other codex's create a balanced fighting force because they are designed too, we must then assume the sisters make a formidable alliance because that is what they are designed to do.
