This is a simple suggestion: take away any effect similar to the ice pick effect at least in PvP. This means Ice Pick, Thanatos Card, Acid Demonstration, etc. I'm not sure if these things have already been nerfed at all since I only recently arrived at this server, but I have noticed that at very least Thanatos cards are in use.
Why take it away? Because it makes fighting in PvP pointless. Either you have low VIT which means you have low HP, and then all the opponent has to do is switch weapons to decimate you, or you have high VIT with high HP, but the HP doesn't matter because the ice pick effect creates so much damage that you die in one-two hits anyway. Take that effect away, considering everyone is going to be having 550 VIT due to the stat cap anyway. It will lengthen battles and nerf physical attackers, which I have noticed have an edge over magic-users already anyway. I might even go so far as to suggest the removal of any defense-piercing effects (Incantation Samurai Card, Combat Knife, etc.) because it will help to elongate battles and make fighting in PvP more enjoyable.
