Its mentioned that it is not recommended because it neuters two of the huge functions of Pex, phasing setup sweepers and winning PP wars. Its usable sure, its not as bad as Merciless, but similarly it is a fundamentally worse pex, plus rather than run double Toxic I would definitely opt for Knock Off which is way less redundant and has way more utility.I mean it’s literally mentioned on the Pex analysis, it can’t be that niche.
