The only issue with requiring a direct hit is that all the people who just fire it blindly at anything that moves will still hate it. Since they need every launcher to have tracking people will still complain about it. I think its fine without tracking and really i think the only change needed is its exotic effect. Instead of that lame solar grenade i think a napalm effect would be pretty effective. Essentially anything caught in the blast radius is set on fire (taking substantial damage from the DoT) and then either A) Sets other enemies on fire that are nearby or B) enemies that are burning deal damage to nearby enemies and stack damage to other burning enemies. For example, lets say you have 2 groups of 3 enemies. The first group is in a line so the one in the middle would take 3x the burning damage while the 2 on the ends are only taking 2x the damage. The other group is in a triangle formation so all 3 of them are taking 3x the burning damage. I think this would make DB the ultimate RL for large crowds leaving Truth excel at PVP and Gjally for single target damage in PvE.
