How much is enough? CRT

So I'm currently working on a 2h tanker and I'm having a major accuracy problem. I can't hit anything, which leads to mp shortage, which leads to no skills, which leads to no aggro. At the moment my stats are 50Vit 111Str(or somewhat around that) and was wondering how much CRT would be enough to Crit decently enough to make up for poor accuracy. As said before this is a tank-ish character so I can't just swap out my equips for CRT+ gear.

 

Dex would raise more accuracy then Crit. I wouldn't add Dex stat in though. Tanks are usually just meat shields and not meant to fight so I don't really have any thought on how this works. I wouldn't really worry about Accuracy though. You are a tank that takes dumb making your pt do that meg for you and you being able to attack is just a bonus.

 

Get astute if success hit ur following skills and normal attacks will crit more often for a certain time period.
