Rogue has no issue on it's own. Commander's strike has no issue on it's own.
Though you are right that it's the combination that is OP. It's also arguably an underpowered maneuver when a rogue isn't in the party.
But just to reiterate you can't in good faith act like it's the rogues fault that commander's strike is OP when a rogue is in the party.
Meh. We have all this already in the game. Add in the Sentinel feat and rogues potentially get extra sneaks. There's more than a few ways to grant off turn actions and the game doesn't seem to be hurting for it.
I mean, you almost never see threads talking about how OP rogues are. You'd think that this would be a major issue if it was so OP. As far as being underpowered if you don't have a rogue, well, you still have the Great Weapon Master raging barbarian in that corner and the Paladin in the other corner. It's not like there's a great shortage of spike damage characters.
AFAIC, that's the long and the short of the argument. Everyone agrees you can get a fair ways towards having all the elements of a warlord in the game already. If we already have all these elements in the game and the game isn't breaking, then adding these elements under the umbrella of one class isn't going to break the game.
To be honest, what we really, really need is something concrete to discuss. All this theory crafting just isn't going to go anywhere. They need to do what they did with the Ranger. Give us a couple of iterations until they get something everyone can live with.
