Try not to prioritize to kill him first. Let him as your last dessert.
But you still can win against terminus in certain map if you have advantages of controlling high place with abbys spike. Use your tp, term cant hit you from far.
To win against zhin, you need better position(high place) and good eye. Look at zhin loadouts first. Dont attack when zhin use counter. Fighting zhin is similiar like fighting koga, both are confusing. But in reality is not, as long you watch zhin.
Koga can be so confusing. But in reality is not. Place your teleport first and Aslong you watch koga movement you can win the duel. Have max shield would give you time to read the situation first between fight koga or enter teleport
