Hunters have the worst grenades. No Hunter grenade can OHK from full health, with the exception of trip mine, and the blast radius for that is extremely small, and rarely will you get a OHK with it. The very first thing you get as a Titan Defender is a magnetic grenade that follows a person and sticks to them for a OHK. Warlocks have by far the best grenades. The first time I saw a Solar grenade, I thought it was the Sunsinger's super!
