Achievement: Something accomplished successfully, especially by means of exertion, skill, practice, or perseverance.
Luck isn't skill. That's reason number 2 of why these multiplayer achievements are not liked by me. Reason 1 is that it alters gameplay for a period of time and doesn't provide a true picture of how a map functions. It usually ends up in the achievements ruining maps and making me dislike them.
I don't really see how luck plays that much of a role. I mean, does the sticky detonator operate on luck? Because pulse grenades are very much like a dumbed down version of the sticky det.
You misunderstand my point I think.
You need to hope that two enemies remain close enough together while no shields for this achievement to even be achievable. The odds of that are unlikely, and even slimmer thanks to the nature of the Pulse Grenade.
EDIT: Did you change your avatar to a pulse grenade during this?
I don't think I'm misunderstanding so much as we're disagreeing. I use pulse grenades regularly, so I have more confidence that the achievement will be relatively simple. As it stands I have 32 kills with them [and 2 deaths] in Slayer gametypes, and I don't generally try to get kills with them. I just use them for stripping shields. A double might be a bit of a tall order, but a single kill wouldn't even be an achievement. And they are under-used, so it's not unreasonable for 343 to highlight them in this way.
And yeah - I change my avatar to match the conversation regularly. Or, well, his face.
You're really reaching here.
Well, both follow a ballistic trajectory, have a momentary 'arming' delay (although I'm not 100% sure that's not latency), and leave an explosive hazard in play for a non-instantaneous period of time. The detonator might be capable of more trap-laying strategies, but if you're firing either directly at somebody, they're very similar. If the nades had a remote trigger, no persistent field, and enough damage to kill with one blast, they would be exactly the same.
