I'm guessing you weren't playing with KBM? But yea I think even with IR's pinpoint accuracy hitscan you still wouldn't want to be firing it from beyond ~120m (I'm having bad flashbacks of the damn "Bow Elimination from 150m away" challenge weeks ago).
Loool. Yea your habit of attempting challenges ASAP is the kind that Epic relies on for trolling. That said, i can relate with the compulsion
There was definitely luck involved with my sweatless GM Raz challenge, I'm just glad I decided to take a look instead of assuming the worst.
Wait, how was that maximum effort? Was it supposed to be minimum effort, maximum payoff? (I'm ignorant about Deadpool.)
