Team SB's arguments here are based on the fact that SB's durability would be too much for Reze to do any meaningful damage in the long run. That is ignoring how small that 2x gap is. That's not enough for him to face tank her attacks with no harm, and she can still very much deal meaningful damage against him. The fact that she has a 3x speed boost is also ignored here; in addition to her flight, Soldier Boy is gonna have a difficult time tagging her in the first place.
Also, the arguments made against her regen are extremely weak. Apparently, radiation should be able to KO her, how? Apparently its because she lacks radiation resistance? Ok? She has high-mid regen, and other hybrids like Denji can remain conscious even after slicing apart their own brains. The fact that Queen Mave, someone with FAR inferior regen than Reze, can tank his blast already makes this point invalid. Even more insane is the blatant disregard of that ability's weakness, the fact that he still needs to build up energy and can barely move while doing it, making it easy to dodge or to interrupt him. Given her 3x boost and flight, Reze can very easily escape, or counter it, and her own ranged options lack such weaknesses.
Even worse is the fact
@Zyurtunder13, who made these points, never once rebutted any of my counterarguments.
To put it simply, SB lacks any way to counter Reze's High-Mid regen, which allows her to easily survive his blasts and LS advantage. Meanwhile, she has a 3x speed boost with her explosions and has far better ranged options that don't require build-up or remaining stationary like an open duck. This is just her beating him up again and again while he couldn't find a way to put her down for good.
