Why are so many people running We Pissed Them Off IV in horde?

I just had a solid group of randoms but someone ran this challenge card and we failed at wave 15. I couldn’t believe there were 8-10 elites on the field at the end and then I remembered the challenge card.

We wasted a lot of time. I queued up at least 4-5 times afterwards and every time, someone chose we pissed them off iv. I had to back out. It’s fine at lower waves but it really bites you when it starts getting harder.

I guess not many people are aware of the mega combo High Threat Environment IV/Plus Ultra. Makes the mode so much easier as it negates some of the increased damage and boosts our cooldowns through the roof.

I’m guessing people see the 2x multiplier on Pissed and they just go with it?
