I think this is just a situation of "if it's not broke..."
I mean, unless someone can give battle reports to show something truly egregious.
The closest I've seen is attackers relying heavily on R5 troops, against cities which lack any, allowing the attackers to win from out of reach. But I've never seen such battle reports, and I've only sparsely heard of it. And... I mean, honestly, sounds fairly legit. "attack the fortified location from out of range" seems like pretty basic siege tactics.
