Is anyone else confused with the existence of individual Z-moves?

I really dont get why they though something like that is necessary when we still know barely shit about general Z-moves.

Not to mention they had to create specific item for just a single Pokemon move and insert them in the games like we haven tgot enough items already. Then create a long-ass animation (seriously Snorlax Pancake takes about 30 seconds) which sounds like a huge waste of time and money GF should've been spending on some cool features or post game

Signature moves were always a thing but since you can use a Z-move once per battle and you need specific item on your specific pokemon to do that is it really worth it? Megas were pushing it, genearl Z-moves are psuhing it but this is just a whole new level of "whats the point"

It will probably make the games even easier and it smells like Yokai Watch soultimate moves for a mile
