Am I the only person who is surprised Latias has not dropped to UU yet?
Before I get a ton of hate for this post, bear with me for a second. I was using Latias recently, and it is just so.... Weak. That's all, weak. I know you're supposed to rack up a bunch of Calm Minds and whatnot, but the more you try to rack up Calm Minds, the more likely you are to get critted. Doesn't it just suck when you've racked up 2 or 3 Calm Minds, and when you go for the fourth knowing you can wall the HP Ices from the opponent's special attacker, you get critted and die? I don't like that. If I were to use any Calm Mind sweeper, I'd use one that can get sufficient power from just one or two Calm Minds, such as Latios or Keldeo.
Another bad aspect to Latias (this applies to Latios as well): Pursuit weakness. Tyranitar can always trap you with ease, and if Latias lacks HP Fire, Scizor completely counters and traps you with ease. In fact, just about anything that carries Pursuit can trap you. Weavile? Yep. Escavalier? Sure, as long as Latias doesn't have HP Fire. Hell, I'm sure I could pull it off with a Scarf Beedrill if I tried hard enough.
Not only those, but... Latios is just better overall. I've used both as a Calm Minder, and Latios I thought was the better one. As for Choice sets, there's obviously little to no reason to use Latias over Latios. Both get easily trapped by just about anything carrying Pursuit, but Latios has more power. Maybe Latias could pull off a more defensive set, but I must ask, why would anyone use a defensive Pokemon that is weak to Pursuit? Why? So, in that category, Latias would be overshadowed by walls that are not weak to Pursuit.
Okay, I'll look at it the other way. Latias is a good Breloom counter! You know who else can switch in on Mach Punch/Bullet Seed? Dragonite. Is Dragonite weak to Pursuit? No. Can Dragonite OHKO Breloom? Yes. Well, sure, Latias can use Psyshock or something, but Psychic is a very bad offensive typing.
Now, I'll concede a little. I have had some success with Latias. But, I've had much more success with Latios. So, when it comes to the Lati twins, clearly Latios is the better choice. So, can someone explain to me why Latias is still managing to stay in OU? No, seriously. When, from my experience, it's just turned out to be an overall mediocre Pokemon, I just don't understand how it's stayed in OU for so long. In my opinion it's better in Ubers, where it can use Soul Dew. But, down in OU, you've got Soul Dew Clause in effect I believe, so that already hurts its potential considerably.
