You should have debuffs if you are 0/5
Damage is nuts everyone knows. But the worst feeling is when that 0/5 vayne starts blowing shit up. It's pretty dumb in my opinion that you can just completely miss play the early game but no matter how poorly you played, if you cs you'll pretty much be as strong as everyone else. There should be some type of damage reduction debuff that you get if you rack up deaths. A 1/7 tryndamere should never one shot you.
