So i main deathblade, i have a big issue with the charge abilities against guardians btw im 460 it.lvl l, so i know later in game maybe i get runes and lvl 3 supercharged but is ok for now to play with the normal cast tripods ; or in general it is ok to play all the game with normal casts versions if that suits me ;
all the dmg is on the charged skills , playing w/o those is gimping yourself
its gets better with more gear 
I see and i figured out i must be a little overgeared for the guardians like im 460 i do the 420 one
