According to me in engineer. Going full int is better atleast at endgame.
Str is good giving a tad but armour rise but that decreases damage and crit. And Dex dexreases Armour but increases damage and crit and dodge. But int has it all. It has got balanced armour ,nice dodge and damage and crit. I went full str in lv40 for pvp was nice. For 45-46 i am full int. If you need more suggestion hit me up in game. Now i am usually mre in my engineer "Scarfaced" or Comm "Unknownman".
