White Magneto Bugged
I just tested out white magneto and he seems to be bugged. Whenever you use the pre-fight with any champion, the passive stun causes you to be pushed back. This makes it really awkward to chain heavy attacks in places such as v2. This was happening in the beta as well and it really reduces the value of his ability.
Another problem is that whenever you use the pre-fight on white magneto himself and you fight against a metal opponent you aren't able to land parries most of the times. The text pops up for parry but the passive stun doesn't. I'm not sure if somehow he decreases his own ability accuracy or something but it only happens when you use the pre-fight.
One final thing (and i'm not really sure if this is a bug or not) is that his sp1 and sp2 animations have been switched. Is this intentional? Because in the beta his specials were the same.
