I’ve noticed that Silver Surfer and Ultron don’t display the little floating ‘immune’ indicator anymore when attacked with a power capable of stun.
Bring it back! It was a nice touch!
It’ll probably come back about the same time as the sparkly victory banner.
We also reverted at some point to the behavior where Silver Surfer is never targeted by random stuns (and wasting them), which means his allies are more likely to get stunned.
