Its hard for me to care about legendaries because I see most as a dexfiller nightmare, especially the gen 4 ones. Too many legendaries either look really boring, really ugly or a bit of both. I think the only legendaries I actually care for are the tapus, ubs and the regis (no regigigas tho i hate that dude).
Honestly im just legendary fatigued. At this point either make pokemon a forces of nature story with the legendaries as the main forces, removing evil teams or dont include legendaries at all
Now I'm curious to see ratios for each generation. Lumping mythical and legendary together for this purpose, excluding forms. Also including Phione.
Gen 1: 5/151, 3.31%
Gen 2: 6/100, 6% (overall 4.38%)
Gen 3: 10/135, 7.41% (overall 5.44%)
Gen 4: 14/107, 13.08% (overall 7.1%)
Gen 5: 13/156, 8.33% (overall 7.4%)
Gen 6: 6/72, 8.33% (overall 7.49%)
Gen 7: 14/89, 15.73% (overall 8.41%)
Okay, quick note, that number is including Cosmog, Cosmoem, Necrozma, Meltan, and Melmetal, but excluding the UBs. If you include them (including Poipole), you get:
Gen 7: 25/89, 28.09% (overall 9.77%)
Gen 8: 11/79, 13.92% (overall 10.02%) [overall 8.8% without UBs]
I love the UBs but they are really bad for the legendary bloat. If you include them we actually have reached the point of 1/10 of all Pokémon being legendary/mythical, that's pretty insane. It's getting sillier and sillier to try and cram all of them in one game without making a separate minigame for them, and even then, I don't know how long that will last.
