No save allowed during story missions = epic fail

FINE.
Here you go in laymen terms:

1: Beware what attack you make for it can cut both ways.
2: YES! Some of us do like to scrounge the battlefield after the battle is over.
3: Good. Ingenious ideas... will make a mod of this if possible ... once I can figure out the Frosty Editor.

The insult is in stating that controllers can't be customized when that is NOT a fact at all.
Anyone with enough electrical experience can take a controller apart and rewire it should they wish another button were to be used.
Rebinding the controller this way is not standard and is surely unconventional and may not be standard to think of but it is done.

I know someone who is left handed who does not like to use the triggers and uses a controller for PS3-PS4 so he turned one into an inverted controller with triggers/flippers removed. He also turned another controller into a steering wheel.


As to shoving memes.....
Childish and a Meme...... 
So to you every picture means it is a meme and childish?
I usually don't respond in text for most either get annoyed or angry or simply rant.
But if you want an intellectual response with out pictures then there you go.

There is a point when such an option may not be worth the effort. Like, when I started MEA, I found that there was no button layout for my PS4 controller that quite suited my comfort level, particularly the arrangement of the aiming and firing buttons and how each option corresponded to move and view toggles. No way on Beelzebub's brown earth was I about to futz about learning the innards of this thing just to accommodate a single game. I'd be better off just acclimating to the setting. 

Beelzebub is another name for the devil in Christianity, also associated with Baal.
