cassiopeia needs changes

cassio is really strong now if you master her but her dps source is ONLY focused on her e , and that sucks . cassio needs a better ratios on her q , better base dmg on her w and a rewarding ultimate ( since its skilled and kinda hard to hit ) , actually she is kinda fine but cassio has some issues . the only good part on her rework its her sustain dmg , it gives her a better duelist potential and survivability . this passive needs to be removed cassio could be fine with : a damage passive or a kind of spells buffs like :
her mana is just fine with a and a + as starter

a snake bites once and see his pray dying . not 100 times until it dies because her poison got cancer
