If this is what you think, then you might want to consider the following points:
1. Forms are meant for learning a style, not for learning how to fight. Learning by rote is a staple of Chinese education. In wen (literary skills), students learned by reading and memorizing entire books. Likewise, in wu (martial skills), students learned by practicing forms.
However, just like someone who only memorizes books without any practice on actually applying the knowledge in those books will fare poorly in a real job, a martial arts student who only practices forms without sparring and even real combat experience will fare poorly in a real fight.
Again, like I said, there wouldn't be so many styles if they weren't effective in a fight.
2. If you think that MMA ground fights are examples of "real fights", think again. Going to ground, in any fight outside of a 1-on-1, is a really bad idea, as you'll be defenseless against your opponent's buddies. This is why in Sanda, they practice throws without following your opponent to the ground. In a real fight, if your opponent is down, and you're standing, you can quickly end the fight with a kick to the head.
Actually, it already become seriously unwise to ground-wrestler as soon as the ground is hard and unregular.
From my personal experience however, MMA is very "pragmatic", most serious MMA-users tend to be more free in admitting their "flaws" as opposed to (especially non Asian) practicioners of East Asian Martial Arts.
The German military (conscripts)has some basic instruction on how to kick people in the groin with a soldier boot, how to hit people in the torso with a Bayonett, with a bit of a (psychological) focus on how to not crap your pants while doing so . This focus involves much shouting ,swearing and laughing. Basically, laughing, shouting swearing and crapping your pants are all very primal forms of stress relief, that differ greatly in their ability to increase your prospects of survival.
As well as a lengthy treatise on why its always nice to have some ammo in your gun.
Apart from that: First (unofficial) law of unarmed combat in the Bundswehr:
"Dont be unarmed you idiot!"
