Useless omicron

Can they do damage? There, only Crusher with the 2nd skill can deal damage to Django under invulnerability.

Not only can Crusher/Wrecker do damage, but if Omega is under Stealth, she will assist. Since everyone else will be under stealth, there's no problem with getting enough stacks of Trample on Wrecker. If you're not killing Jango, it's because you're clearing those stacks of trample.

But it's not only that. Echo has this unique:

Whenever a BadBatch ally inflicts a debuff on an enemy, that enemy loses 8% protection. If that enemy had less than 50% protection and more than 50% health, they also lose 8% health.

I don't know why they coded it this way, but this ability is coded as "negative healing" rather than damage, which means that it bypasses Jango's healing immunity. The reek is immune to % health healing as well as % health damage, so it is unaffected by all this. As a result, even if Wrecker never picked up an extra stack of trample, you could still reduce Jango to 42-49% health while waiting for that extra stack of Trample to happen.

Sure, it's possible to kill the Reek first, but if you focus on dealing debuffs to Jango, and if you don't cleanse the Trample from Wrecker, and if you DO cleanse the trample from Omega, well then you're going to tear through Jango.

Stop by 50ShardsOfKAM on discord and you can chat strategy with people who use BadBatch all the time. And after next month we should have some footage up of the new Omega Omicron in action.
