As Jax in say a 5v5 teamfight and I jump onto a carry, should I keep my Counterstrike activated to dodge their basic attacks or should I quickly tap E again to get the stun?
Situation dependent. Are you being focused by the ADC? Can be helpful to hold the dodge. Has an enemy got an ult or ability you can interrupt? Maybe save it.
Should I keep the Counterstrike up or quickly use the stun in teamfights.
