And yet... there's the Battlemaster standing right there. With nary a quibble.
Complete with non-magical mind control - "Goading Attack" (regardless of the tactical situation, I can force an enemy to attack me), "Rally" (regardless of what your character thinks about my character, my battlemaster can inspire you and give you temp HP), "Maneuvering Attack" (I hit an enemy and you get to move your character. How? I dunno).
But, again, it falls below that objectionable threshold so it's fine.
It does make the conversation REALLY hard to take seriously when ten powers became this HUGE issue and even the idea of "martial powers" is a problem too when people are perfectly happy with martial powers in 5e - many 5e fighters and rogue sub-classes have all sorts of martial powers, and have no problems with the same things appearing in 5e.
It's such a minefield. I'm not allowed to question why it's fine in 5e, but not-fine in 4e. There's some sort of magical threshold beyond which there are "too many" changes. Which, when you think about it, explains the 5e playtest a LOT. They started the playtests with big changes. Got feedback, and then walked back those changes until the feedback was suitably positive. WotC has proven pretty adept at finding that magical threshold and then toeing that line.
