I'm finding it's too much of the same and offers a lot less variety not having the previous generations available.
What has lost me with this generation is the nerf on my level 1 Mimikyu (focus sash is no longer useful) and no endeavour on Togedemaru. No Smeargle. So there is no (worthwhile) level 1 shenanigans.
Then the Pokemon I would use aren't available. No Magearna, Diance, Meloetta, Stakataka or any of the Mega's I'd use if we're talking DOU. Lando-T and Kyurem-B I found neither overused, broken nor difficult to deal with. Incineroar was overused last gen but otherwise I found in DOU there was a lot of variety and add in the new mechanics and there would be some more lifespan. I'm already feeling like with this generation I'm largely done with it while generations past with the mechanics and variety of Pokemon I never found the gameplay/variety got stale like that.
In saying that DUbers is my preferred format and requires the full complement of Pokemon available to be interesting. And seeing Zacian/Zamazenta in their crowned forms and Eternatus would have been wild against the other popular Pokemon used in the format. And add gmax Pokemon to that along with Primals, Mega's and Z-Moves and that would really be fun in a doubles format and re-engage me and the other DUbers players from generations past.
honestly i'm mostly a cartridge player for wi fi battles and VGC and stuff. I come here for ideas in the current meta and play with stuff sometimes in showdown. But honestly after having JUST gotten masterball rank, i'm seeing a lot of the same stuff in online ranked. 9/10 teams lead with whimsicott in upper tiers. several excadrill leads cause he covers a lot of common leads in dmax often paired with ttar of course. However there were definitely some suprise teams that really made me smile. but overall most of the teams got to be pretty predictable with the same pokemon. Originally I wasn't super salty about dexit but at least in ranked play (partially because of streamer's rental teams), many of the teams run similar comps and already after season 1 am wanting more variety and just adding G-max pokemon to the mix I don't think will solve it but I could be wrong.
I'm really hoping for DLC or maybe a sequel with nat dex at this point. Will be curious to see what comps I see in higher ranks of masterball tier if I decide to pursue that.
