Unbreakable is currently only able to be held for 5 seconds, even while sustaining massive damage. It seems to be a 4 or 5 second limit. I believe it started last week, but have noticed, tested and confirmed it today for sure. No note in the patch notes about this change, so I'm HOPING it's unintentional. Any insight on if this is intentional, accidental, and/or a fix timeframe would be appreciated! It's the BEST new addition to Titans in a long time, but not being able to rely on it to do what it's supposed to do kind of defeats the purpose.
