Any of those grenades stop health regen for 14 seconds? Any of those grenades allow you to track the enemy you hit with almost pin point accuracy? No. And yes im excluding those grenades because they deserve a one shot, if you can nail someone with it they should die instantly, use the titan magnetic grenade that is the only one that does not instantly kill you and is the biggest waste of time to even use. If all fusion grenades were not one shots you would never see them used anywhere in crucible would be better to replace it with a stick of butter and expect them to die from that. If your saying fusions shouldn't be a one shot i have lost all hope in you.
