Your theory is not right, because you are forgetting about Jewelry and Magic Defence, including magic defence buffs/dances. There are also resistance buffs/songs/dances. We realize that whoever has the most CON loses more from CP, but still that’s all there is to it. We can’t fix things based on theories. Once we get some PVP action going on we can then balance things out.
Please refrain from theories and only post stuff that has actually been tested. We already had 2 people fighting over things that weren’t even tested, so let this be the last one. Once we go live, it doesn’t mean that nothing is changing.
