I use Valkyrie in almost every arena fight I do, but recently enemy units have been randomly ignoring shield. No blue text appeared saying Ignore Shield And Block Damage, and this happened with units I know for a fact don't do that skill one, such as Dark Athel & Skullcrusher. I checked through the masteries to see if there was anything I was overlooking, and I didn't find any. Either there is an error with ignore defense, an error with the bonus damage against shields mastery, or hackers have switched to using this method (though I feel that one is the least likely of the 3 with how often it happens and the randomness of the units that do it) Can someone please advise me as to what is going on.
