ngl, while i was adamantly anti tb ban during the suspect but ive come around to seeing it as a very valid path, moreso than a zac ban imo. while thinking about its impact i made a list of mons/sets that we would lose as collateral from a tb ban to rein zac in, remind me if i forgot any.
- Zac (other sets)
- Emu (other set + bad)
- Eleki (other set + bad)
- Poisonceus/Arceus (not real)
- Random DD Sweepers (unhealthy)
- Spectrier (other sets, loses scarf sets somewhat)
- Offensive CM Magearna
- NP Deo (bad)
While personally am not *against* the idea of a TB suspect, I think i am very much against pushing for a tera blast ban > a Zacian ban right now. I'm not going to argue that the existence of tera blast isn't a part of Zacian's current strength, but I think when Zacian is currently the only user of it and it isn't even present on all of its good sets is certainly something that should be considered. I think that Tera Blast ban could be a solution, but I dont see why its the direction that should be taken when (if we are going by an ubers standard) I think it makes more logical sense to target a broken pokemon and not a move that really just effects said broken pokemon. If Tera Blast was actively more an issue across more pokemon i would be more supportive, but I think campaigning to ban tera blast explicitly to keep one mon in the tier feels like a questionable approach to trying to manage this tier in my opinion, and I don't think thats an unreasonable thing to say.
While Tera Blast can exist outside of zacian, Zacian is one of 3 real users (two of which are exclusive to niche sets and pretty well broadcast on preview in spec's case and pretty easy to figure out when you see a mage set up) and by far the most dominant one. Its notable to mention that when the last tera blast suspect happened, while i didn't play the meta actively then there were 3 notable abusers of it at the time in Zac, Chien-Pao, and NDW. If it wasn't banned then when you could more argue that TB was a widespread issue I dont see the reasoning for re-testing it when only one Pokemon is actively effecting the meta with it. It makes much more sense to focus on something like Zacian and getting it out of the tier if it is indeed unhealthy instead of having a suspect test of "The best zacian sets".
Again, I don't disagree that Tera Blast can be problematic, its been a huge part of Zacian's own viability, but from my understanding of tiering policy here it doesn't make sense to ban Tera Blast in a meta where only one Pokemon is actively problematic with it. Tackling individual moves feels more apt when its centralizing around certain playstyles (webs) or multiple actively broken pokemon (see last TB suspect test). At this point i probably won't be too upset if Zacian doesn't get banned, but it is frustrating to see all the conversation around it constantly circling back to trying to nerf it in some way out of a desperation to keep it in the tier. I think it is a vital part of the metagame right now, but I don't see how blocking action to cling to a hope that if it doesnt get enough support to ban it will somehow get enough support for a rather unjustified suspect to nerf it is just going to keep us in the same cycle of arguing about what is broken in this tier and getting nowhere.
Banning zacian will rather obviously change the meta a lot, its a pretty significant piece of what makes the tier click right now, but if it goes that does not garuntee the meta will not reach a point of stability eventually. No suspect ever aims to fix the tier in one fell swoop, and as a majority of people seem to think there are some issues in the tier (be it zacian, tera blast, sleep, etc) I think that when the option to take action and enact change arises, is the best step forwards.
Edit:
Just wanna add a comment about how i think its a bit hypocritical to say zacian doesn't warrant a ban as it isnt broken in your opinion (which is fine), but then to say that action should still be taken to neuter it in some way when that action is even less worth of a ban in my opinion at an ubers level. if the meta is able to adapt around Zacian and manage it offensively, we shouldn't be devoting resources to make it "more healthy" if it isn't outright broken, at which point why not support a ban?
