Vampires of 7th or lower Generation may have permanent Trait rating of 6 or higher. It is pretty easy to roleplay physical attributes at such levels -- you are just stronger, or quicker, or your flesh is more resilient to punishment. It is very easy to play any stat mechanically -- 6 is just one die more than 5. 

However, I prefer to move the game without actually rolling dice, so the story isn't determined by luck, just keeping character traits in my head and, taking rough estimates of rolls that I calculated by AnyDice into account (sometimes), describe what characters are capabable of doing. And there ***is*** a problem when it comes to pretty much all other stats at levels 6+. 

Let's say, a character has some experience with guns. He has 4 dots in Firearms, and I tell the player that his character is an experienced sniper. He has 1 dot, and I tell the player that his character was instructed on how to load the gun, but didn't actually have any firefight experience, etc. 

What is it to have 6 dots in Empathy? In Survival?

Any Trait at 6 dots means something beyond the ability of a human. How do I describe capabilities of such a character?

The question becomes even more important if one player starts with 7th Generation, which is possible in Dark Ages, however, such powerful characters may enter the chronicle as NPCs at any time.
