Should mythical be allowed in gyms?
At least, I would like it
Answers
The motivation system ENSURES the very experience of the game makes all efforts useless, so this is a totally unacceptable factor to determine why Mythical or Legendary or Scary Pokemon should be at gyms.
They shouldn't be there because they shouldn't. They are LEGENDARY. Are you forgetting the word? It is a Pokemon one should never see in multiple lifetimes. Something many don't even believe exists. There in fact should be a cap for ownership of any Pokemon outside the regulars: 5 max inventory , 3 max especially for attacking.
And for the stupid, no, VERY stupid people below saying "it would be a valid way to keep the game fresh". No. that very notion is the epitome of fleeting. Its just some indulgent measure that kills the longevity and process owed to the Pokemon universe: work extremely hard for the greatest achievements. AKA "the harder the battle, the sweeter the victory". The very idea that people enter battles with a TEAM of Legendaries should force you to question such shamelessness. And it's not even an idea, its a worldwide reality.

Nope, you're mixing up legends with mythics. The general way that things go in the Pokemon universe is that legends are known to exist, and in many cases people even know where to find them (the Tapus in gen 7, for example). They tend to fall into one of two categories: powerful Pokemon (The legendary birds, the aforementioned Tapus) that are generally on a par with more powerful Pokemon (mainly the pseudo-legends; Dragonite, Tyranitar, Salamence, etc), and the "big" legendaries like Mewtwo, Ho-oh, etc. The greater legends tend to be absurdly powerful and the focus of their games.
Mythics, on the other hand, seem to be Pokemon rumored to exist in-universe, but they're so rare that they haven't been studied in-depth, and as such are poorly understood.
In general, mythics are weaker than than the greater legends, normally falling to the power of lesser legends or pseudo-legends. There ARE exceptions to this, such as Arceus, or Marshadow, the later of whom is mainly considered hugely powerful due too its many MANY advantages.
Note that this is all from a main-series perspective.
They could have had something like the elite 4 fight, except you have elite 6 and then 7th is the champion, who can use a legendary if they want. The 7th will probably be the one who took the gym first and is saved for last unlike the other 6. You'd have to kick out the other 6 to get to fight the 7th.
Speaking about legendaries; from the 5 remaining ones in this generation, 4 of them are defensive-oriented (Latias and the Regi-trio). Since they’re not quite useful the way the game is now, I doubt people will be really motivated to keep raiding after catching the first one (something similar happened with Suicune in the latter days, at least here). So, less motivation to raid = less premium passes being sold.
Would be a different story if legendaries were allowed as gym defenders.
I'd be very happy for those to be released, so that I can finally focus on Tier 3 solos or Tier 4 duos. Raikou, Ho-Oh, Groudon, Kyogre, Rayqaza and now Lugia are too valuable source of candy, power and raid rewards to spend passes and raid anything else, and my raid group is consistent enough to get 2-3 of them every day of the week. Yes, I would actually like a calmer legendary pace for a while, but something tells me there will again be Latios and the birds re-released to keep us hardcore raiding Tier 5.
If Niantic kept the old gym system with key elements from our current gym system implemented into it, I would be fine with legendary Pokémon defending gyms. Some of these elements could include, but are not limited to:
-One of each Pokémon per gym
-One legendary Pokémon per gym (only possible to place a legendary in a gym if you have a Gold gym badge for that gym)
-Order of Pokémon based on who places their Pokémon first, second, etc., and not CP based.
-The structure of the old gym system should be brought back, rather than what we have now with all the Pokémon clamped up together, it's just not visually appealing
-CP decay removed, and prestiging brought back, so you can always battle Pokémon at their fullest potential
-Berries (limit of 10 berries per Pokémon like it is now) can be used on gym defenders for stardust (20 stardust per berry). You may even potentially get a candy from the Pokémon you feed berries to, so berry feeding will no longer be an issue since CP decay is removed, and is only associated with collecting stardust and candy
This isn't perfect (since spoofing exists), but this kind of gym system sounds a hell of a lot better than the one we have now. With the current gym system, I'm just not okay with legendaries defending gyms. Gyms will just be filled with legendaries only, which will stale their presence. Plus, no one wants to battle a 1000 CP Groudon or 500 CP Mewtwo, that's just too lame and easy. Until Niantic cooks up a better gym system than the one we have now, legendaries should remain exclusive from gym defending.
EDIT: Mythicals included
