You should move around when facing a bomb king and if he gets you low then try and get near your team, BUT don't stay too close since he does splash damage and it could hurt real bad.
Use Pursuit only when the enemy is low on health since it doesn't do as much damage and if you don't kill them with it you could possibly die,since you are vulnerable and aren't doing as much damage to kill them.
As Kinessa try to juke him. An easy way to do that is to jump to the left/right between your shots. But zoom out when your jumping so you have more movement speed!
You should put a mine at your current position or at a point where you know he MUST come around. As you hear your mine you have 2 choices: 1.you kill him 2.you use your teleport to get away I would recommend to teleport to/near your team.
