Before the Atlas update which I don't think I will bother with-
Formation 1, 3 and 4 are all worthless, actively hindering you
Both radiation and infinity negatively impact the game (let alone shite 'infinity' scaling)
'Fast slash' buff is also an active detriment, there is nothing 'fast' about it.
Extremely irritating that Conqueror resets completely every single time you fight space.
Was okay for a while, but I don't think I'd say it's good anymore at this stage [Could second infinity within probably less than a day]
-Ps, level xp requirements reduce based on rebirth points, and there's a whole radiation upgrade path that gives you more rebirth points kind of for specifically that - Rebirth points are now hard capped at 100K - you will always hardcap before you even reach that radiation upgrade, why cap it off.
