Control with Defender Titan is great. Run Armor of Light. Anyone coming in your bubble is dead. I've straight up punched a bladedancer to death inside my shield. If you happen to have the Helm of Saint-14 then anyone coming inside your bubble will get blinded and you will also be nearly indestructible so you will win those fights most of the time. Use either Magnetic Grenade or Suppressor Grenade. If you stick someone with the Magnetic Grenade, they will most likely die. With Suppressor Grenade you can prevent people from using their supers, throwing grenades, using special melee abilities, and even double jumping.
