Is scarlet witch still bugged, why not everyone esle is

RO53TT1

So I've been playing this game for 3.5 years and alot of that time I heard alot of people talking about scarlet witch being bugged but I thought kabam had fixes this a while back, so my question is when scarlet witchs power drain buff pops up is it supposed to drain the opponent power and scarlet witch's power? Seen this 100+ times using and fighting scarlet witch and just now in the 4* basic arena I was fighting scarlet witch, power drain buffs pops up and my power and scarlet witchs power both dropped to zero, if this is supposed to happen then disregard and close this thread but if not this is sad cause I know the bug has been in game for atleast 2 years.

She has power drain which zeroes out both heroes power and she has a power steal, which does exactly what it says,
