Which turned out to be the case, as we can see from the patch notes. 
So, was it a lucky guess or something else? 
In case there are actually some ‘community reps’ reading this, let me tell you that: trying to be the ‘white knight’ doesn’t really help. I mean, sure, you’re probably just doing what you’re told, having obtained a cheat sheet with simple instructions and taken a course on being ‘positive’ and ‘constructive’ — but still, this semblance of toxic positivity is not what’s needed. Sure, there are people with negative attitudes, but many — like the author of this topic — are actually giving constructive feedback, some of us are quite passionate about the game, a few on this forum have also done an impressive job testing the game and reporting (documenting) issues — I wish all of that could be said about the developer team… So, when the community gives such good feedback as Darkmoor has, for example — and I think anyone who has played Mercenaries extensively would see the point — it would be best to listen, summarise and deliver it to the developers, not imitate a battle bot going into the defensive mode. After all, sometimes the community is actually doing,as said, the developers’ job, such as testing — how smart is it to not only brush them off in such an insulting manner under the veneer of ‘positivity’, but also squander this resource, let alone the small matter that they are also your customers?
As for testing, as mentioned previously, — sometimes I get the impression that they don’t play-test the product at all. For instance, there was this: Mercenaries: some (heroic) bosses not as talkative anymore . I don’t know if it coincided with C’Thun’s event (just looked it up — it happened during the same patch 24.0) — the one that appeared to be somewhat tested and free from critical bugs for once, — but I wouldn’t be suprised if the developers, who finally play-tested some bosses, got annoyed with their excessive eloquence and disabled it.
Who’s laughing and where? Let’s stick to facts and not wild guesses, assumptions or figments of imagination, shall we?
Besides, there’s absolutely no shame in looking things up for anyone. I tend to do this regularly on this forum in order to be precise with certain specific details, for example —
