Battlefield tactics make the kind of ranged attacks applicable without the large chance of losing your archers for it.And actually, you are forgetting something...You can both move. You aren't an impassible wall. Thus a step and switch is easily done.

Even if that were so (Which it is not, you have a huge Minotaur and a near equally large centaur in question.), then you're invalidating your own argument, which was that our cannoneer could not quickly move back behind Gryff.

EDIT: Add in that I'd already had confirmation from Brovo early on in the mission that the corridor was only just big enough to accommodate them, and that was the entrance corridor. So while this corridor may be different, I wouldn't be betting my gold on it :p
