As stated in Killjoy's description, she's supposed to punish bad play and people who don't want to take the time to watch out for her utility. Problem is, after nanoswarm took a major hit (which imo wasn't needed and only happened because people are bad at the game and like to cry whe they can't blindly rush a site every round without repercussions), you can simply... run through all her utility and only take like 20 damage? The buff to nanoswarm DPS was a step in the right direction, and as Riot said, they want to rework Killjoy to give her more identity as a bunker-down-and-hold-a-site character. Now that alarmbot can't be used for global intel, it needs a buff to be able to create a threat like it's meant to. People run through it without even bothering to listen and then shoot it on reaction. My proposed buff is: before it gets triggered, it has the same health as it currently does, and can be killed in one shot. But once it's triggered, it should become a lot more tanky (maybe half the health of a boombot?), so players can't just tap it once and keep going. Make it so that it's a lot harder to not get vulnerable'd after rushing through it, and make it so Killjoy can have the opportunity to capitalize off of it.
