Hot/Unpopular Take
Waterpon is not getting banned. Kyurem is not getting banned. Neither is Tera Blast, or Kingambit, or Gholdengo or anybody else. I don't think any major metagame bans are going to occur after this point. The dissatisfaction for the current metagame and overtly broken threats are just not there for it.
Some of you have this dream that we can one day have fresh, thriving, diverse balance structures in this tier. I recommend you give up, as I have. As long as tera is here and the current hazard chokehold with ghold and co exists, we're always going to be funneled towards bootspam structures that have been thoroughly explored already. Banning waterpon, kyurem, tera blast, etc will not save balance or improve the tier. All you're doing is taking away the few tools HO has left to beat ting-lu BO.
Tera was never going to allow defensive playstyles to thrive. There's simply too much to account for. So if you all want to embrace tera, you also have to embrace offense, and work towards ensuring that HO stays as viable as BO. Balance is a lost cause, and if you try to save it by banning wallbreakers, you're just going to end up with a dominant BO+weak HO+weak balance metagame. I would prefer if a variety of playstyles were at least roughly equally viable.
All of the above are my predictions based on my teambuilding experience and subjective opinions on the metagame, none of this is some objective unshakable truth. Nothingeverhappens.jpg
