I will talk from healer aspect…
From my experience 90% of my lost rounds are resolved around guys who die without using their defensives… Examples: mage dies without block used, pala dies without bubble used, lock never used mitigation, hunter dies without turtle etc, or guys use mitigation when they alredy have 5% hp left… or people use major defensive abilties for nothing while not even threatened, I saw ALOT death guys with all of their toolkit aviable but unused.
Solution:
Each class have its own major defensive ability right, is it hard to make algorytm which snapshot in which conditions player died ? For example if guy died and his major defensive is unused, healer and others from his team shoud lose at least 50% less points per this round.
Right now entire SS is resolved around that one guy who steps in then die like bag and eat damage like turkey eat corn, we are all in mercy of this guy some healers more than others but all suffers, and overall his impact on outcome is high and it shoudnt be. Something must be done there…
