Change the presentation of the battle to a more interacting one, were you see your pokemon running in a field and you stay outside and give attack commands to them. Thus the core mechanics would stay the same.

No

What they could do is something like Dragon Quest Monsters Joker, where you can see the Mons and approach, surprise them from behind or avoid them, but that's about it

I think you don't quite understand the meaning of the word "fad". Pokémon is not a fad, if it is on its 20th anniversary. It has outlived the Walkman and the iPod now. A fad dies. Pokémon is not.

What Pokemon could do too give it a slightly more real effect is too allow the trainer to move in battle, kinda like dragon quest 11

In my opinion, it should. Or at least do something different. The way I see it Pokemon has been the same thing since its inception. People talk shit about CoD or FIFA of not innovating enough and being the same thing every year, yet most give Pokemon a free pass. 

At least Pokemon has it's new unique charecters designs with unique backstories for each, lore wise. And although gun nuts will tell me otherwise, new fps games are same old same old. Same thing slisghtly different stats

And if you say every pkmn game is the same old thing, you can say the exact same thing for most of the jrpg gente as well.

Action rpg pkmn should be a thing, but either as a side game or a second version.

For example, XY as traditional and Z as action, or X as traditional and Y as action...

Itd be nice if something evolved into an action rpg. Preferably something a little more serious, but id take what I could get at this point. Some of us would really like more than just zelda and metroid as far as top tier action games from nintendo. I keep harping on about a star fox 3ps, but thats because I really enjoyed star fox adventures which I played 4 the 1st time last year.

After playing the new God of War I'm down for gameplay changes, so I'm all for it if Pokemon changes too.

Obviously some people dont like change and can be stuck in their own comfort zone, but if done right it just gets so much better!

To all Nintendo fans that said "No" to this: You all love Nintendo for their innovation and changes in their consoles, so why don't you want to see that in their games too? Like if you were at the helm to create your own Pokemon game would you not want to do something different or you'll just copy what Gamefreak has already been doing?

Innovation can be done in others areas than the battle system. Would you want to make a compatible action rpg move set for 900 Pokemons? It's not that people do not want change, it is that changing the system would be a hassle, especially when it has worked for 2 decades and has a competitive scene. 

I have nothing against the battle system and it is great as it is.  But who's to say it can't be better if nobody's actually trying something different?
