Nah, the problem with Q is holding it too long throws commo-rose up. BF3 is set-up to have Q/spot function work as squad commands and squad-want ("I NEED AMMO!") along with spot for consoles. It's like that on PC as well but if you hold Q for longer than like 1-3 seconds commo-rose pops up because PC players whined about having Commo-rose and so DICE threw it in, but it's really apparent the game doesn't need it.
And I think I like 1942's F1-12 spot/command function better than Commo-rose though hitting F1 to spot infantry was pretty awkward.
