Ok I am going to charge straight into this debate like a new player flying straight at me with his sheild down.
I disagree with any changes to the current set-up. Most of my PVP encounters do not last that long and when I encounter someone skilled then yes the fight can drag on but I always take that as a challange and a mark of respect. The majority of fights though do not turn out that way. I am a bit concerned tampering with the balance is playing with fire.
If you simply tire of a fight against a skilled opponent then withdraw, escape is also a skill.
