We really need a clear list of what is bannable

[Zeratul]

Again, if they don't die, that doens't happen - so that's a glitch caused by enemies for killing these heroes (panda/phoenix), therefore ban should be applied to them - logic!

[Sylvanas]

I guess one could argue that they're not abusing glitch on purpose because they're not dying on purpose.

Disclaimer: This excuse is only valid if one isn't also feeding and game throwing. Sylvanas is not responsible in case of bans.
