What? I strongly disagree with this post. Scizor is a metagame defining threat. It’s really great and has multiple roles but CAN be beaten by strong Fire types, physical walls that can deal with such as Alo and Pert, and even can be hit really hard by strong attacks such as M-Pidge Hurricanes and Hydro Pumps from Primarina and M-Blastoise.
M-Latias is defintitely unmanageable. A Pokémon does not need to be extremely powerful to be unmanageable. It’s versality and sheer bulk alone allows it to basically swallow teams whole and turn them to setup fodder. Seriously, you say there’s ways of beating it, but you didn’t even list these ways. Dark types are beaten by the Reflect Type and Roost and can be stalled out of their Dark STABs until they’re setup fodder. Even Primarina, has to lose some of its health just to beat it if it’s BoltBeam. It’s unpredictability just makes it even more insane. You literally have to toxic this thing or pray your opponent is bad or misplays or it’s all over for you if it gets free turns to CM. And last I checked, nothing is really preventing it from doing that in this tier.
Hah you sure told the tier leader!
In all honesty, Hogg brings up a good point with the issue with Late-Game Latias. Outside of its late-game potential, you also have it kind of functioning as a pivot in the early- and mid-game From the battles I've played and spectated, the norm is almost always CM and Stored Power, but the last two slots is what makes the Pokemon manageable. You essentially have three options:
1) Avoiding Status/Checks (Refresh, Reflect Type)
2) Recovery (Roost, Recover)
3) Coverage (Thunderbolt, etc.)
Since you can really only pick two of the three, these options can be scouted out in the earlier phases, and once that is determined, you can play around that base on what your team has prepared for at the time. As Hogg said, because CM + SP variants need some notable team support, you can
mostly deduce what variant of Latias you're dealing with (Utility or Sweeper) based off of team composition.
For Defensive utility, I think M-Latias is at a point where it's really good, but not to a metagame-constricting point like Mega-Steelix was in RU.
The biggest problem that is suspect-worthy for Mega Latias is that its non-mega version is also a top-tier metagame threat, and since you can't tell whether the Pokemon is a mega or not (especially since Z-Crystals can't be removed by Knock Off to check), the Latias most of the time gives its user the upper hand in this case.
If we combine all possible roles Latias and Mega-Latias can play, you can add wallbreaker to Hogg's list, and that last set can get around Latias' counters i.e. Empoleon. However, this is almost always an incredibly minor point because most of the time you can tell if Latias isn't a Mega Pokemon by the presence of something like Aggron, Sceptile, etc. in the opponent's team preview (unless you're in low ladder, then good luck). This is only in the case when you see a team with no obvious mega Pokemon and with Latias.
Also, not an insult, but I swear, the people shouting for a M-Latias ban are much better off as Creative Writing majors given how much they love to use colorful language to over-dramatize Mega Latias.
