I was looking at YBT's video and his damage seems pretty good for a character without strikers on WBU, and fighting Cull, who's the second beefiest WB after Thanos.
Overall, I think he'll be a decent WBU clearer (best used against Maw, due to the elemental damage, naturally) and probably a good pick for TL in the weeks Jean is banned. There's also the fact that he and Emma are now eligible for two XAB days and might score higher than Magneto. Also, we have to consider that he's very easily farmable, so can't make them too strong or the whales will be mad LMAO
Emma looks great, YBT had her do some good damage to Maw without strikers and proper leadership. I'm pretty happy for now. Since the metagame is unforgiving, at least we'll be able to have some fun with them in most of the modes before power creep hits for real. Just avoid TL as you should LMAO
