Credit mega pack worth it?

I personally never got any multiplier the few times I bought the 8 packs. That was when I was starting out and have never bought again nor am I going to. I clear GW everyday and have a good roster so I'm able to manage resources just a little better than I used to.

My wife bought her 1st 2 8 packs today and got a 2x multipler on 1out of the 16 packs. She's really getting skewered in GW so she went ahead and bought them. Only top 5 toons maxed so having a hard time getting her roster upto speed.

So are they worth it? Depends on how bad you need them.
