It just sounds like you're not good with the Hunter and should try something else. Both Warlocks and Titans can die mid super animation. Both Titans and Warlocks can have their teammates wipe out a group right before their super hits. A smart Hunter activates his GG around a corner whilst he sees the enemy team is capping a flag. Long story short, it doesnt need a buff and Warlocks and Ttans dont need to be nerfed. They all have stregths and weaknesses. You just need to figure out how to adapt.
