I think the next round of trailers or streaming content will feature more about them. From the last stream, WW, Cheetah, and Bane's are definitely worth the effort. The grind is real but for no debuff for Bane or double buff for WW it is certainly understandable
Most of them seem to be related to Gear.
I have my own ideas >
.
Aquaman: Aquaman's trait now drops him directly out of the air from airborne combos.
Atrocitus: Dex-Starr's recharge is decreased and Atrocitus's attacks consume less of it.
Black Adam: Black Adam's trait now hit as regular abilities.
Black Canary: Black Canary's trait is now unblockable but take longer to recharge.
Catwoman: Catwoman's scratches are given on every claw attack.
Deadshot: Deadshot has a 4th trait option: Vampire Bullets, which drain half of the health damage dealt to enemies back to Deadshot.
Doctor Fate: Doctor Fate's ankhs now affect the entire visible screen, and Sharidum's Lock prevents the use of Super Meter.
The Flash: The Flash freezes his enemy in place qhen his trait is activated, but the start up and recharge times are increased.
Firestorm: Firestorm's trait starts in each match at 3 bars.
Green Arrow: Regular Arrows now deal increased damage and travel faster than any other arrows.
Green Lantern: Green Lantern's trait now recharges twice as fast and lasts twice as long.
Harley Quinn: The start-upon her trait summons is decreased and the recharge decreased.
Poison Ivy: Poison Ivy's abilities now employ a poison damage over time to enemies after the original damage. Or. Poison Ivy's trait now fires much faster.
Starfire: Meterburned Trait now stuns enemies hit for a short time.
Supergirl: Supergirl's trait no longer has to recharge but using 4 + R2 will remove the ability to use the trait at all until it is fully recharged for twice the recharge time.
Idc if they are OP, it's meant to be.
