Technology in the MCU. Is it just me?

[Karmasux96]

Tony's been transitioning to a more mobile suit since IM2. Seems perfectly in line with the evolution of his tech and, frankly, was expected in IM3. Since he built Spidey's suit, it makes sense he'd use the same tech (poor Rhodey with his government-issue suit).

The real issue is that Spidey needs to keep his mask on. Way too cavalier with that in A:IW.

As for BP? The problem isn't the vibranium nanotech, it's that he's completely invulnerable in his suit until villains start figuring out the vibration weakness.
