Gene takes 80%+ from a Choice Specs Draco Meteor from Latios (and is 1hko'd by Surf in the rain). So with Latios you either have to run a Pursuit user, something else that can handle it, or lose a Poke everytime it comes in. Maybe its just me, but i feel like most stuff that can handle Latios have poor synergy with Genesect (Ferrothorn, Scizor, Blissey, Jirachi...only Tar has decent synergy).
Irrelevant. A Genesect user isn't going to directly switch their Genesect into a Latios; it's way too valuable. Rather, it's Genesect's ability to consistently revenge Latios is important. Latios activates an atk boost on Genesect, so it can use U-turn for free. I actually bothered to do the Draco Meteor calc, and it's (70.3% - 82.7%) for -SpD & (62.9% - 74.2%) neutral SpD. Genesect is one of the few scarfers that can be counted on to switch into Latios which is more than what I can say about... pretty much any scarfer in OU barring Jirachi.
Salamence becomes more effective with Gene running around because Scizor useage is reduced, and like you said Mence outspeads at +1, meaning you have to run something like mamoswine (or another scarf user) to check it. The bad news doesnt stop there though. Against Mence you are practically forced to use Ice Beam, and then your good friend Magnezone says hi. And god forbid it predicts the Ice Beam and Mence lives.
It isn't any more effective than before. It appreciates the the lowered Scizor usage (it's still somewhat common) but BW2 also brings Scarf Thundurus-T / Scarf Keldeo and a ridiculous increase in Mamoswine usage. In any case, +1 DD isn't revenged killed by Genesect, which is definitely a point in its favor. If it hasn't boosted though, its easily revenge killed. And please don't bring hypothetical battles into this; I don't want to get into a pointless anecdotes.
Dragonite is in the same boat as Mence, except Gene outspeads at +1. However, Genesect gets an attack boost, and therefore cant 1hko through multi scale. Dragonite procedes to set up another Dragon Dance (and outspead, btw) and then threaten a 1hko with Fire Punch.
Actually, Dragonite got hit hard by the existence of Genesect. Ice Beam won't OHKO through MS (that's a given) but you're almost always going to revenge kill it when MS goes down, which is basically the point i've been trying to make.
Sub Latias was already amazing, and Gene cant be counted on to revenge that.
?
Sub Latias isn't amazing, and Genesect is beating that on average. Unless you're running Sub + 3 atks, and that set is just straight up outclassed.
Hydreigon probably got a little worse, although Hydreigon is rather outclassed anyways.
On what planet is Hydreigon outclassed? And why would suggest that sub Latias over Sub Hydreigon when Hydreigon can actually somewhat bypass Genesect with Fire moves? Way to kill your credibility.
Haxorous is kept in check nicely, but it just got a bunch of new toys and is best used under Duel Screens (imo).
Pretty much every set outside of CB is fodder for Genesect. DD & Scarf are terrible now. The fact that Genesect OHKOs Haxorus after it kills something isn't that big of a deal to me because most teams should have a Pokemon that reliably revenge kills Haxorus anyway. I'm actually glad when Genesect switches into Haxorus Outrage, because it means that it won't switch into battle as often when rocks are up. (If it switches into any other move... lol)
I strongly disagree. Just about every dragon got better because of him, and this is why:
Listing Genesect's matchup vs every Dragon type isn't going to prove anything. You're looking at things in a vacuum. Consider the bigger picture here;
Genesect is reliably revenge killing every single Dragon type in OU and it's extremely common too. No single Pokemon could do that before. Hence why I said Dragons received a nerf. Its not huge nerf, and Dragons are still top tier but Genesect is something that should
always be considered when using them. I was actually kind of hoping that Dragons would get nerfed in some way in BW/2, and we got one so yay me.
+Spe Scarf Genesect can outspeed and OHKO Neutral +1 Salamance (Rash / Naughty seem to be the most common natures) so even Salamance gets RKed.
I can count the amount of Jolly Mences I've encountered in one hand.
Everyone should be using +Spe natured Salamence in BW2. And if they aren't, they will.

I've held back on my overall opinion of Genesect, but I think it's time to shed some light on its absurd power upon merely switching into battle. If you call Excadrill "undoubtebly Uber under sandy conditions", then you are simply are not paying enough attention to Genesect or much of OverUsed at all.
It's very fun to use; unfortunately, it's very irritating for the other side, and that's more important. Even if you have a check to it, it still doesn't make it any less irritating because of U-turn / different sets. You deal with it by running multiple Pokemon that resist its coverage moves, and by running some hard checks (Gastrodon + U-turn resist is what I typically use). I don't think it's broken though and i'll fight tooth and nail to keep it in OU, but yeah I consider it the best Pokemon in BW OU with practically
0 flaws. All of the best players are going to be using this thing.
