[MCU] Spoilers for episode 5. Did Wanda just massively shift the power balance of the MCU?

Massive Spoilers, not kidding, turn back ye jakanapes.

So in the newest episode, Wanda brings in Quicksilver from Fox's Xmen universe to replace her dead brother. If that QuickSilver has the same power, isn't he now like in the top 5 strongest of the MCU? 

He dosen't have any defenses against mind control or magic so unless he speed blitzes Wanda or Dr Strange and kills them instantly, he loses to them. However any Physical characters like no glove Thanos, Thor, Hulk, etc, cannot touch him with the speed he has shown.

Foxes QuickSilver is one of the strongest mutants ever shown. Able to detect an underground explosion from a couple 1000 feet away the milisecond it started, speed laughably faster than sound, strength far above captain america, he completely imbalances that universe.

A) We're not actually sure Wanda did it. There may be something else manipulating her or boosting her power. 

B) It may be that the local laws of physics are different in this universe, and Quicksilver will no longer as godlike as he was in his home universe. 

C) We're not actually sure that's the Quicksilver from the Fox X-Men universe. It may be a regular person from Westview who has been brainwashed into playing the role of Wanda's brother, and the fact that he looks like that version of Quicksilver is a coincidence.
