When she comes back, she'll probably go back down to earth some. She had the obligatory big splash from her introductory appearances, but she did not seem unbeatable or trans level.
Diana's godly weaps were never portrayed as supremely durable during N52. Her swords broke all the time. Her braces twice. Heck even her shield was trashed. Full disclosure I think her shield was trashed by antilife. But still, no question Pre 52 her gear seemed tougher.
Her bracers took a prolonged and concentrated blast from Grail. At least that's how it looked like in the art. She did kill reincarnated Darkseid. Very plot devicey the way it happened , but still incredibly impressive. We also had Barda's beta club blocking her omega beams quite easily so there's that to consider.
I'm not ready to anoint her as an out and out team buster trans leveler just yet. Need to see more. If she was portrayed clearly above heralds then that would be something different.
