Re: Re-introducing COM to 6th Edition
rjcurrie has already named the other way of doing COM: Describe how your character looks, then let everyone else decide if that is pretty or ugly.
Presence is a very abstract "how impressive am I" stat, similar to HP (Body) or EGO. If you want to abstract COM as far, you end up wit PRE. If you abstract a bit less than that, you end up with limited PRE, and if you abstract as less as possible, it's probably best left to SFX (after all, the Fire Blast and the Iron Spikes Blast cost the same, even though Fire is a lot more beautiful) or some incredibly complex construction involving Mind Control or Transform.
I'm not trying to convince you to drop COM. I'm trying to convince you that limited PRE is the best mechanical representation for it. You may still write it down as COM, starting at 10 (equaling +0 PRE), and going from there. I really don't see any better way to use COM in game terms. It does not make you stronger or faster, it does not directly give you a reputation, it does not allow you to do damage, it only makes you more pleasant to look it, which is essentially a function of PRE. You could even go as far as to separate PRE into two parts, such as "frightening" and "lovely", where the first one is used for "FREEZE" type attacks, and the second one (COM) is used for Seduction.
And yes, you may houserule as much as you like. I only recommend not doing it for COM, because you're not gaining anything, you're only introducing unnecessary complexity.
