I have two suggestions for ice:
1. Sham can't ice mice after death
I would like this to happen because on double sham maps, when one sham dies he usually ices mice going into the other sham's hole.
2. Speech bubble appears even when you are iced
What I mean by this is when you get iced, you can still see the speech bubble above you when you type something in the chat box.
Tell me what you think!

1 - is intentional. sucks, yes, but it's intentional.
2 - makes no sense, you're basically dead. that's like jumping off the side of the map and wanting a speech bubble from the edge of the map.
