Just occurred in a recent match, DW was frozen completely for the full duration when hes suppose to have Unstoppable
This is correct. Ice Wall is a Time Stop and therefore can affect Deathwing. This is consistent with other Time Stop effects like Void Prison and Ley Line Seal.
Ahh i see thank you for the Knowledge Drop,
Makes sense how the theme of being frozen is basically a stun throughout the game, so having a “Time Stop” attribute is surprising
