Any chance we could get the ward to ignore small damage? The reason we've wanted a ward for so long is because we wanted a tool to help prevent people being one-shotted. We already have plenty of tools for dealing with hits < 50k. It's a small change that would really maximize the effect of this ability. First two ideas I can think of would be to make it ignore hits for less than X percent of the person's health (like many stoneskin effects) or make it only ward damage that would bring the person below X percent of max health (like the new defiler ward).
If you removed the "mob must be below 50% hp" requirement, this wouldn't be needed. In it's current form, however, we'll have to use Interrogation on an add being burned down to get the ward to activate. It's not difficult, but we'll have to hope the timing works out well. I'd hate to use it on an add 20 seconds before an aoe, and then have little hits slowly eat the ward away before the aoe actuallys lands. If we could get the ward regardless of mob hp, then we could just time it ourselves, but you aren't giving us that option right now.
