I've said it before and I'll say it again, if you think Tera should be untouched because it's a "generational mechanic" then you better be playing your Gen 5 matches with Wonder Launcher enabled
Lol, nobody is saying it should be untouched because it's a 'generational mechanic', they are just saying that there should be a higher bar for it getting banned if people want it (they don't btw 25% is not enough and there is no silent majority, also not because its worded "wrongly" also, because it is worded exactly correctly which is do you want to restrict tera or not and do you want to ban tera or not, its simple). Also, comparing tera to the fucking wonder launcher is honestly, just laughable.
I don't think tera should be banned, defensive tera is a godsend in this meta where covering all meta threats is difficult and bans are very difficult to acheive (I'm a bit shocked that volc was banned tbh). Sure, offensive tera, and tera in general, raises the power level, but not many mons are made broken by tera. Only Regieleki, Terapagos (who had its own fucking form), Volcarona and Espathra (who I think would be broken regardless, others think otherwise) are broken due to tera (most are due to tera blast, so a subset of tera at that).
I think
RS25802580 put it perfectly, any mon that can offensively threaten you is answered by defensive tera. Waterpon beating your ass? Tera dragon starts beating her ass. Roaring moon acrobating all over your team? Tera steel your tusk and watch that mf die so quickly. Barra is liquidating your entire team, even resists? Tera water your moltres and then hurricane that bastard. Without these defensive options, these threats would be so much harder to deal with, I'd say we'd have to ban more things if tera was banned, now there isn't a button to click if a defensive mon wants to wall it. Every mon that has/might be banned is because it was banworthy even without tera (again, besides a few).
So it then becomes "why are we banning a whole mechanic just to bring back a few mons that we banned?" And I don't know, but that seems a litlle wrong.
