Here's the thing: If you hit someone directly with a Pulse Grenade, it is not necessarily an instant kill. If they are damaged, it probably is. If they can't get away, it probably is. If you hit someone with a sticky grenade, its always an instant kill. That should not be the case. The 'one hit kill' META of D1 was left behind for a reason. Shotguns, Snipers, Fusion Rifles, Heavy Machine Guns, all these things were changed or removed to rid the game of the 'easy mode' Crucible. That 'easy mode' Crucible promoted advantage leveraging that made interactive gunfights less common. In Destiny, kills come from skill, and teamwork. In D2, the emphasis on less powerful abilities adds more interaction and reaction to situations, which makes the game more skill intense. For example, camping with a shotgun kills instantly, and is not skill intense. Camping with an SMG, kills quickly, while still offering outs to the opponents. There is more opportunity for skilled play without feeling like abilities are too powerful. People say that skill was removing from Crucible in D2. That's not what happened. The game is more forgiving of 'mistakes' or disadvantages, but skill remains as relevant as ever. Teamwork is only more relevant because abilities are less relevant due to damage and cooldowns. 'Teamshooting' in Destiny 1 was far more difficult to handle than in D2, its just more common in D2 because of how much more efficient it is. With all that being said, Grenades probably need to be buffed in damage, but Resilience needs to be more relevant as well. If Grenades go back to D1 levels, we go back to a META dominated by Warlocks. D2 doesn't need to be reverted to D1, it needs to progress and realize its actual vision for gameplay. D1s vision of gameplay was finally realized in AoT, from what I heard, and D2 needs to have the same thing, but it should be done faster. Its already started off in better shape, and needs only minor adjustments, including Grenade effectiveness, to really realize its vision.
