I'll lay this out one more time.
The force users have the following ways of attacking the wizards:
1. Force pull/push. Easily escaped by apparating.
2. Force choke. Easily escaped by apparating.
3. Force lightning. Easily escaped by apparating. Besides, the wizards will never get close enough for the force users to use this.
4. Force crush. Easily escaped by apparating. Besides, if we go by screen feats, Vader can only force crush what is in front of him, and to his left and right, and he must target his attacks. Also, he can force crush no farther than he was shown doing. 10 feet radius, if that much.
5. Saber attack. The wizards won't ever be this close.
Force attacks can only range as far as what we see onscreen. Never, not ever, is a force attack shown with a range of hundreds of feet (which is a distance the wizards can easily attack from, even far beyond that.). Not counting Vaders force choking Ozzel from across the galaxy.
Now, again, the precog. If Vaders precog was shot in ANH when he was focusing on Luke, when Han surprised him, it will be shot here, what with all that will be going on.
In the end, the force users have nothing that the wizard cannot counter easily.
Prove me wrong on these facts.
