They could be padding the roster every update with non-guardian versions of the monsters we only have guardian versions of like Fulgur Anjanath and Ebony Odogaron: They're literally the same movesets without the environmental absorption stuff, and they could be in different areas.
Is it cheap? Yeah, but it's still fucking content. Just make them endgame equal armors with those same bonuses. People would adore endgame Anj armor with the bonus stamina for exploiting Max Might.
And once those are out of the way just give us the normal versions. Regular Anj and Odo. It'd be less work than entirely brand new monsters and while maybe not great additions people really want, it would give us SOMETHING in the mean time at least...
