Well remember that not everyone has Kat, even though most do due to Game Pass. And, like I said, people are incentivized to play as the original six for achievements and ToD medals; playing as the Reach characters, Terminator characters or COG Gear doesn’t benefit you in the same way as playing Kait/Del/Jack/Fahz/JD/Marcus.
Within that restriction of six characters, Del is the only engineer, because for some reason even though other classes can build other things, they can’t upgrade them and they can’t repair them without spending 10k. Then Jack, as you mentioned, just has too much going on for him. Not having a Jack player is essentially a willing handicap at this point. (Which I actually kind of enjoy, but that’s me.)
You might have a point about Kait/JD being OP, but honestly, I’d still sway more in favor of Fahz/Marcus being UP. There’s no reason for Fahz to not be able to get a kill off an active headshot on a drone in Elite on wave 11. At that point, why even have a sniper.
