Whether your mods are mk5 or 6 doesn't matter if they're crap.
Drop your swgoh.gg link, let's see your mods, your zetas. Record a video and put it on YT, let's see your strategy.
This is the same flavor of post I've seen on this forum since O66 was launched and I have every reason to assume that your mods are bad and your strategy in the raid is bad because it has been demonstrated repeatedly, by numerous people, with video evidence, that BB2 do just fine in the raid if you know what you're doing.
