PSA: Stop throwing all of your spells at the first person to get in range.
There's no reason for 
to be feared, stunned, knocked up, exhausted, and silenced all at the same time. The duo assassin comp is so deadly in low elo specifically because people don't understand this shit. The first one goes in, soaks all of that "focus", allowing the other to go in and get a free pentakill.
because you know all the CC before he has even gone in. At least if you are the ADC you have the excuse of there is plenty more damage where that came from. CC on the other hand is crucial and being blown on random or on people it doesn't effect is terrible.
