I would like to give my point of view on the matter of terastallization. I have seen doomerposting about the end of the tier, and I believe that sentiment has been fueled by the decisions made since the initial tera test. In my opinion, the council's actions have been aimed at forcing a second test rather than improving the tier itself. Now everyone seems to clearly see that Gambit is too powerful, and that banning Gambit would cause a domino effect that would require banning Pult, then Dengo, and finally Zama. Wasn't this known four months ago? So why was Zama evaluated when player surveys indicated that there were other more problematic mons? Then Ape was quickbanned (for those who argue that Gambit cannot be quickbanned) with virtually the same score as Gambit, which wasn't even tested. Later, with the release of HOME, the council quickbanned Ursaluna instead of Sneasler. Decisions were being made, but those decisions did not contribute to balancing the meta but rather created a feeling of overwhelm until people began to massively demand a retesting of tera. And now what? Will measures be taken to move forward, or will a third test be sought? I understand that council members may feel uncomfortable with the voting results, but we must be fair and try to move forward for the good of everyone.
That being said, I would like to invite reflection. In this tier, we are slaves to very inflexible Smogon rules that should not be applied so strictly in this case. The problem of terastallization would have been solved in a balanced manner if it was tied to an item for terastallizing. Most tera-abusers rely on their items, and if we equate tera to z-moves and megas, its effect would be moderated. To terastallize, a mon couldn't carry a choice item (solving the stacking effect of tera stab on mons like Barra, Float, Zama, Shifu...), nor HDB (Volcarona or Dragonite would be vulnerable to rocks), nor focus sash (Polteageist), nor seeds (goodbye unburden Sneasler), nor covert cloak (Mew and Cress), nor WP (Latios), nor toxic orb (Gliscor)... In this way, the number of tera users would be indirectly limited to one or two per team, they would be easier to scout, creativity would be maintained (no spoilers on preview), and it would still be useful for mons that can do without items, like Valiant, Tusk, Heatran, etc. This is not an official tier, this metagame cannot be played in official games, and the mechanics are not intended to interfere with each other. The rules of allowed moves and items are arbitrary and should be subject to change if the community agrees. Let's not be slaves to our own rules and appeal to common sense and logic.
