It is generating hard flux, yes, but have you checked how pathetic it is if only one rift it generated?
Rift cascade beam is a CQC weapon in first place.
Also, are you using console command or some other mods to summon all the desired omega weapons or what?
I don’t think a “standard” fit should be using omega weapons in first place. They are good to have and some are OP, meanwhile they are not guaranteed to be obtained especially large ones.
You may theory craft anything of course but that’s just unrealistic.
You are also missing solar shielding, hardened shield and the shield modulation in your formula. If you were to fight remnants it’s common sense to use solar shielding. You also did not take combat readiness induced increased shield efficiency into account.
On top of that, the missile spams and the short time your shield off after teleport has high chance getting weapons shut down by either sabot emp or hammer torp brute force damage. It’s bold to assume you may have full damage when you’re in range.
Just to make sure, we’re talking about player radiant efficiency versus player guardian efficiency. A guardian with autoforge can mop up an entire ordo. Can a lone radiant do that? Radiant is going to be 60 DP next patch, so if radiant can’t do that we’re looking at at least Ziggurat or more DP cost to be “balanced” for a “vanilla” guardian.
