I'm a dodger and In some fights I Block or Crit more than I dodge.
Unbuffed, my base stats are:
Agility - 357
Intuition - 76
Protection - 42
But there are things you can do other than buff to increase these stats. Things like runing your armour, activating talents and using certain potions in battle.
BC set doesn't guarantee you more crits in fight. It has more to do with your opponants strengths and weaknesses than you think. For example, if I was to fight a HW player with fully runed, Reflecton + SoG set... I'd probably crit more than I'd dodge because HW set is strong vs dodger stats and weak vs BC stats. Chances are if the HW player was as strong as me with similar skill and potions, I would lose the fight because of the Fighting style bias.
Equally, if I was to fight an equally strong BC player with valour armour, I'd dodge a LOT but I wouldn't block as much.
The set bias goes as follows.
Dodger > Bonecrusher
Bonecrusher > Heavyweight
Heavyweight > Dodger
But this is just a guide. Just because I'm dodger, doesn't mean a BC can't kill me in a straight 1v1 fight.
I know it's comnfusing but I hope this goes a little way towards explaining the basic stats and game fight mechanics!
