Lagiacrus and Agnaktor are both in the same monster class (Leviathan), so of course they'll have similar movesets. But Lagi is aquatic and Thunder-elemenatal and Agna is subterranean and Fire/Ice/Water-elemental (counting Glacial). What you said is basically like saying every Flying Wyvern after 2004's Monster Hunter is a recycled Rathalos.
