Re: Avengers 2 and X-Men DoFP are both using Quicksilver and Scarlet Witch
One of the reasons Whedon said he's putting the twins in is because they have actually visual powers. According to him almost everyone on the team is "Yeah, I can smash the heck out of things" but Quicksilver and especially SW are different. While Quicksilver technically is still "smashing" things his speed adds a different feel than anyone else. And seeing SW's powers done correctly on screen is worth their inclusion alone if you ask me.
