Interest of waiting for meta?

Hello,

I can read a lot of people waiting month (year?) without pulling and stocking rubbies for ‘meta’ characters but look there are less and less content so is there’s any interest for a F2P player to wait for so powerfull unit but without content to achieve (basically some EX3 fight that could be achieve without them even if it’s harder)?

Actually i use to pull or upgrade characters because i like them or they can cover something i miss (like tanking, healing, cover a weakness i don’t have) and so live with them for some weeks, month or even more because they help for something. I'm not very interested by unit that can do all and/or get rid of weakness strategy that is, from m’y opinion, the heart of Octopath Traveler games and make it so interesting but maybe i miss something or it’s the way gacha used to evolve ?

I assume that goal is to make people continue to spend money but i would not be more interesting to have unit with specific mechanic, exotic gameplay or using unused characteristics rather than broken unit?

Thanks

NB: sorry for bad english (not my native language).
