It is absolutely ridiculous trying to complete this quest using the last word. Especially since the meta is so special heavy. The amount of kills you have to get in a row without dying to move up 1% point is unrealistic to most of the community. Majority of the time I sit at around 35% on it and then next thing I know I'm back down to 0%.

I hated the quest too, but I have a solution for you. Use whatever weapons you like until you get your super. Then, switch over to last word, use your super, then immediately switch away before you even have the chance to die. Gives you the kills without giving you the deaths. It's a cheese but if you want chaperone it's 100% worth it.
