Like he said, a good all-around face with commanding voice is better. A pornomancer is good at one thing which is a mixed blessing ("You seduce the troll. Soak 5S damage").
Like any good OP build, it has things the GM might question (Does geneware let you get the revised Attribute maximum at character creation? This also assumes the optional rule that biosculpting can raise Charisma. Do social skill modifiers really apply to commanding voice - and if they do, what about all of the modifiers for things like not being in the chain of command or being an enemy? Can heightened concentration really negate social modifiers? I don't have DG, but either that is a very liberal reading of the power, or the power is very poorly written, because that makes no sense).
The problem with hyperfocused builds is that they sacrifice versatility for overkill. From a gaming perspective, they are boring - you succeed without fanfare every time in your specialty, and can't meaningfully contribute outside of your specialty; a recipe for boredom. From a metagaming perspective, it is self-defeating, because builds like this draw negative attention, and you get hit with attacks designed to overcome your nearly-invincible abilities, or target your weak areas outside of your specialty. Even good GMs will do this, to challenge you. A lumbering troll tank with 52 dice for soaking damage will get hit with missiles and kitchen sinks. A troll with 28 dice for soaking damage will fly under the GM's radar more; he is tough but not invincible. And the second character will be likelier to have more initiative passes and better combat dice pools because he is not focused solely on damage soaking.
