Metagross is not the ONLY pokemon thats restricts teambuilding... banning gross will not result in variety or creativity... ppl will still use helmet lando or defensive chomp, av tang or helmet tang, toxapex, ferrothorn and what not... its gonna be the same thing regardless of whether gross gets banned or not... dnt tell me the rise of helmet chomp is "variety and creative" that set has been used throughout oras and is still being used... and when u say "variety and creative" what pokemon do you have in mind?. the tapus are the result of gross checks being shaky... slowbro skarm celesteela are all beaten by koko (zone traps celesteela/skarm/ferro/scizor) regardless of gross having tpunch (and zone was used in oras to support gross)... helmet tang gets beaten by lele, av tang gets 2hkoed by specs lele and scizor is beaten by pyshic into hp fire..(regardless of gross having zen).. so i dnt understand how banning gross will help advance the meta in anyway.... its still gonna be the same.. when aegislash got banned in xy pokemon like mega gardevoir heracross pinsir medicham all became better... but how does banning gross make any pokemon more viable? U wanna know whats variety and creative, the post that shows stealth rock explosion metagross.. thats creative... not using standard mons over and over again and then blaming gross for lack of creativity...
I value that you have an opinion and I appreciate your desire to make the meta competitive through your contributions. I think your points are valid, but I will gladly clarify and counter them, if you won't mind. Again, I appreciate your counter to what I said, and I do not intend to devalue your opinions, I simply want to try to strengthen my statement. I hope you'll read my comment!
MMeta reaches the same speed as the lati's (350) and is able to outspeed the only relevant dog mon, keldeo. While these were more threatening in gen5/6, it's important to note that the majority of mons in the metagame do not outspeed these aforementioned pokemon. On top of that, we see exactly 7 relevant OU pokemon that have a base speed stat of higher than 110 in our current metagame. That means that a pokemon with a base stat of 145 attack, the 8th highest in the current metagame, will be punching your pokemon in the face first unless you're using one of the 7 pokemon that outspeed it, or have a pokemon that has boosted its speed due to using choice scarf or other means. Not only that, but of those 7, who happen to be Mega-Beedrill, Greninja, Tornadus-T, Tapu Koko, Mega Pidgeot, Dugtrio, and Scolipede, only 2 of them possess STAB super effective moves, and 1 of those 2 is a STAB that attacks MMeta's weakest stat, its spdef. Greninja is what I'm referring to here. Lets look at some calcs:
252 SpA Life Orb Greninja Dark Pulse vs. 0 HP / 0 SpD Metagross-Mega: 268-320 (89 - 106.3%) -- 31.3% chance to OHKO
252 SpA Choice Specs Greninja Dark Pulse vs. 0 HP / 0 SpD Metagross-Mega: 306-362 (101.6 - 120.2%) -- guaranteed OHKO
All right we have 1 check to Metagross. Which just so happens to be a pokemon that rivals it in usage and I'd venture to say is next up on the ban list for this gen. But there's another issue here.
The other 6 mons require specific sets to handle Metagross because of its base 150 def and base 110 spdef. Lets look at the only other STAB super effective user that outspeeds metagross: Dugtrio.
252 Atk Dugtrio Earthquake vs. 0 HP / 4 Def Metagross-Mega: 192-228 (63.7 - 75.7%) -- guaranteed 2HKO
This means we need a Ground Z-move to kill metagross with dugtrio, one of only 7 mons that outspeed metagross. Oh and by the way, there goes our Z-move for our team.
Beedrill is a high base attack pokemon that learns knock off, lets look at the calc for that:
252 Atk Beedrill-Mega Knock Off vs. 0 HP / 4 Def Metagross-Mega: 112-132 (37.2 - 43.8%) -- guaranteed 3HKO
That's pathetic damage. I've made my point.
We have to tweak sets on our team and devote special roles or risk using pokemon that may only have 1 role in our team, that role being to deal with Mega-Metagross. It's difficult to deal with, regardless of the set, specifically because of the high base stats it has. I don't want to go into the kind of damage it does because when looking at the pokemon's movepool and ability, it can make perfect use of it. This is what I mean by this pokemon limits team diversity. I hope this makes it a little more clear.
