An adept with combat sense seems extremely skilled or supernaturally aware (which he actually is). One of those guys in combat who is always moving and everything seems to barely miss them. Thematically is looks pretty badass. The only advantage that armor has is that if they don't do enough damage with the hit to beat your armor value, any damage suffered becomes stun. After your first few runs, however, you can purchase a 'run kit, which you can include some nice, not so legal, combat armor. When you know you are going to be fighting heavies, you put that on, and your combat sense will still help, whereas a few points of mystic armor will give diminishing returns at higher armor levels. If the armor fits more thematically (you see your guy as more of a brute who wades through combat instead of dodging) then go for it. It may not be as great as combat sense, but it is still ok.
