we need streak as stam sorcs- its core to our gameplay, just as cloak/fear is for NB's, armour, talons is for Dk's and ritual is for stamplars- i.e. its how we mitigate damage and survive.
stam sorcs dont get many class melee abilities- so u gotta rely on guild skills like caltrops and trap. playing into ur strenthgs , mobility and separation is key to being a good stam sorc.
