While we could argue all about how you could maybe due with less, and what is your dex and do you use light heal and blah blah blah. I think lotsa vit is fun and it makes you more able to explore different styles of game play. Groups, ofc always doable, solo some big baddies, pvp either dueling or arena. You have a few more options. I been getn by with vit from gear lately and unless I'm in a group at a boss im pretty much useless. Do what ya like. If it suits you to change it, only a rebirth away. Don't ever let people say things to you that dictate what you do. If they don't like it, that's their problem.
