Did I use that as the main centre piece of argument?
Basically I am saying he has a few flaws. I'm not saying that that is the main reason as to what is pulling him back from Ubers, but I'd still consider it one of them. Personally I find Mega-Kang to be a bigger threat with his boosts, good sweeping potential and bulk, but I don't want to stray off topic here.
And likewise, you say "Counters like Ttar amd Psychic-types to a certain extent will most certaintly be taken care of" but not everything goes a person's way in a Pokemon battle, especially if you are versing someone just as good or better. They are obviously going to want to keep them around etc. blah blah blah
I am sorry that I realised this late, but I am not about to go over 23 pages of posts, although I have gone over quite a few and read many of the different arguments floating around. And in the end a lot of this is based on what people have personally witnessed etc. Some people are going to see at as a bigger threat than others, I don't see at as too big a threat worthy of Ubers in the end, you might. I have reasons, you have reasons, and we might both look at them in different ways, I don't find that either points are illogical. There are always going to be debate etc.
And on the topic of debate. The response you made to my first point that the Mega-evolving turn is irrelevant I would have to disagree with. It is like Prankster Mega-Banette, and it does affect the effectiveness of it. "He needs one turn to get the ability up and can threaten/protect during that turn, and most likely switch out, making it a non-factor" I don't quite understand what you meant by that by threaten or protect or the switching out part and so am going to respond as how I read it. The point of a switch will generally be on what you predict your opponent to do, and as quite a few Pokemon can switch in on Mega-Geng without taking over 50% health as long as it was predicted right or is tanky enough to just tank it without much risk, hence I don't feel that it strongly "threatens". I'm not sure what you are meaning by "Protect" that turn, as the only real things he can do to protect would be to Substitute on that turn, granted it is running it, and would be good for it. The switching out part is where you confuse me the most as I read that as switching out on the turn which it Mega-evolves which isn't possible. So I assume you'd be saying the next turn, and that is what I tried to cover. Your opponent may get a free turn if it is forced out for whatever reason, which there are a few because his counters aren't limited, and then can get a free move of setup, whereas Mega-Geng doesn't really have any setup outside of Substitute, which may aid it a lot in the next battle but if the Geng user doesn't setup a sub, there could be problems. In the meantime any counter measure has the ability to setup with entry hazards or a boosting move or whatever, as Mega-Geng isn't a good setup. This in the long run could result in the opponent's advantage.
In your response to my second point. I am by know means saying that his SpA isn't BAD, but it there is still BETTER out there. For those who are using it for SpA sweeping which I have seen the majority using it for, that may not be the best way to go but these are based off of my observations of the sets which I have previously experienced. In the terms of the sweeping spectrum (regardless of whether you don't think that is his best role it is definitely one that he can fulfil well and will be seen around I'd assume) I experienced a Mega-Gengar which switched in on my specially defensive Vaporeon (which was fully invested in SpD so not to Gengar's discredit). I am not sure of what the EV or nature spread of this guys Gengar was but his Thunderbolt did not do more than 50% of Vaporeon's health, whereas a Scald did over 50% of Mega-Gengs health and he was forced out. This may not be the best example, but it shows how even walls and somethings which Mega-Geng can be around to try and be rid of can deal a significant amount of retaliation to it in certain cases. This is an example of a wall which is Mega-Geng's job to get rid of which he isn't up the task for, somewhat showing that he is somewhat drawn back from the role of taking out walls in order to let other Pokemon sweep without perhaps sacrificing himself with Destiny Bond. I just can't see what he shines at so much because of this. I have never really felt overly threatened by Mega-Geng.
And I like how people say "a good Mega-Gengar player should not do this or this" as if the game of Pokemon is just as easy like that. With Pokemon being such a diverse game filled with chance and millions of possible situations, it is hard for you to pinpoint what a user of a particular Pokemon should and should not do. Granted there are some obvious scenarios where it is very unfavourable for you to do something, but it is a lot about prediction and chance as well. You cannot have a perfect Mega-Geng player so please don't make comments like "I would have always gotten rid of so and so first" and that everything will go your way because it doesn't. You can't ignore a Pokemons counters because you have another Pokemon which makes up for it, because it doesn't always match up enough like that.
But basically what I am saying as an end result is that Mega-Geng's counters are not limited unlike for example the 2 pokes who were just banned, Blaziken and Deoxys-N. Those 2 were very hard to stop and got away with too much, Mega-Gengar doesn't do this to the same extent. A good player should be able to take out at least 1 or 2 of his/her's opponents pokemon, but it generally doesn't get too much better for Mega-Geng, and a lot of other OU Pokemon have similar capabilities. A good player should also be able to deal with a Mega-Geng effectively as well. In the end I consider Mega-Geng to be OU material and thing like Blaziken and Deoxys-N to be bigger threats and more ban worthy, out of personal opinion.
