Should i put some into vit? I got a ee plate for lvl 55. Make a tanker or just stick with str and dex?

u can be both

id recommend putting first 5-10 into bc i like getting more life but if u feel u got enough life dont need to

ee for catas

str/dex armor for arena's

Adding vit, only really depends on how much EE is on your armors. If they arent a decent amount then its not worth it. I always suggest just stating str/dex and at 55 you want around 100ish dex with your gear on

Armor has i think 113 ee on it.
