Which means you should be up in arms over threat concerns that break part of your class, rather than trying to continue kneecapping hybrid dps from viability, which doesn’t even accomplish the goal you are trying to accomplish.
Warriors, have more utility than rogues in a threat free environment. They have shouts and can offtank. Beyond that, they even wear a lot of the same gear… and yet they don’t fully replace rogues despite having all this vaunted utility, and honestly even higher dps…
Your rogue will be just fine, if they get hybrids performing up to par (par again being utility + damage = total value)… and your rogue will be in very high demand if they actually revert the broken threat changes designed for naxx, and make them into a Naxx specific zone buff, because your utility will actually work properly.
