Found it.
…This post was made in response to your question last month. You got your answer.
Dude, I don’t want to be mean, but I noticed you asking a lot of questions which were already answered either last stream in a way that made it clear there will be no new development right now (like the mythic weapon one; Nimhain was VERY direct with that one) or you got your forum answer. A lot of people have a ton of questions about things coming up. I like your question about the new game mode and all and would love to see that in the chat. But already-answered questions will just cut the time short for new questions. If Nimhain didn’t give you an ETA or a confirmation, you won’t get any now, either.
You know the devs hate ETAs (for good reasons) in general.
And with things they’re uncertain they want to implement as well.
Right now, they are obviously trying things with the planned raid bosses immune to these things. Doesn’t that already count as “looking into it” for you? To see how it goes if troops can block these things? To be it totally does.
