How would you go about remaking Ruby/Sapphire/Emerald

I don't understand how you come to this conclusion. Look at mega kanga, it's ability made it so a fake out+ any neutral move would 1hko a monster.

Mega Kanga just got banned to ubers, but while it was OU, it was a pokemon that would beat you at Team Preview if you didn't have specific countermeasures for it. And even then, you usually had to sac something to take it out. Fake Out was pretty trashy. PuP, Return, Sucker Punch, Fire Punch/Crunch/Earthquake beats entire teams.

I'm not sure if you know how they define tiers and Corn; can correct me, but it's based on essentially how it, percent wise, affects the major combatents in the metagame. That's why in random matches on smogon theres level scaling so that you don' win simply have a rayquaza on your team.

Why would you even say this if you're not sure yourself? OU is based solely on usage with a cutoff (usually top 50 most used). Ubers is OU's ban list, not tier in of itself. UU:BL::OU:Uber, RU:BL2::OU:Uber, etc. Random matches have nothing to do with this conversation, so why would you even mention them?

In this case, politoad's ability with swift swimmers became banned because mon's became necessary to counter it, a monster with 40+ positives and less than 5 negatives is going to have whatever strategy taken away.

No, just no. Aldaron's Proposal and the resulting complex ban came because you COULDN'T counter it when used by good players. It'd be fine if it had counters. And no, Ferrothorn, Jellicent or whatever else you might be considering were not counters as they were quite easily overwhelmed by multiple swift swimmers.

Talonflame, which I'm sure is on your mind as an example in this discussion, has plenty of counters, where it still adds team variety and balances him within the tier.

I'm actually of the opinion that Talonflame restricts team building (hyper offense with frail pokemon) by having such a powerful priority attack, but to each his own.

Weather teams meta was the worst meta I have ever experienced. There isn't a single counter that can affect a weather team, that a weather team hasn't already saved a slot to counter-counter. You're essentially trying to blame the ban/nerf on unexperienced players, when people who could play circles around you, notice, plural, decided on this because the game was considerably skewed. In fact so much so that the frekin company changed it.

Don't put words in my mouth. The majority of the things that were banned last gen were inherently broken. LMFAO at you mentioning Game Freak in the discussion as if they cared about 6v6 singles or any of Smogon's tiers. The nerfs to weather and special attacks were to balance doubles, where weather has a much larger impact.

you point out why TTar is a usable pokemon, but say that a team around it is gimmicky? You mean for his sandstorm ability? Weather abilities have become essentiall a buff for burst damage. In fact we should see more fire teams since charizard Y/Ninetails are both auto weathers.

That would be obvious if you'd read my post again. You don't see sand stall teams any more largely because perm sand doesn't exist. If sun teams become popular, that'd be awesome; they they'd just be much more limited than they were in the past. Growth Sweepers with Chlorophyll, Solar Power users, and Harvest abusers would just be less viable due to the much shorter timer.

To be honest I'm not sure if you understand how the metagame works, everyone with half a brain know that Goodra was specifically made for politoad rain support.

Developer intentions are irrelevent. Maybe I don't have half a brain, so tell me how many Goodra are running Hydration in OU and VGC 2014 (Nintendo official doubles)? 10% and 14% respectively you say? Yeah, that's what I thought. And you have the audacity to throw around ad hominems and question my knowledge of the metagame...

But alas, I've steered the thread off topic, so I'll leave with this. If anyone explain to me how XY OU promotes more variety in team composition than BW did, let me know through PM.
