Right now, when an enemy denies a tower, a game message will say something like "Axe has denied a tower!" Usually this is ok, especially if you can see the hero/tower as it is denied. But if you can't keep your camera over that tower, it can be an issue. Worst case scenario, every enemy hero is missing and they have 3 towers in deny range. I believe most, if not all announcers, use the same line for all tiers of towers too, so that doesn't help.

Easily fixed by changing the message to "Axe has denied top tier 2 tower!" or even "Axe has denied top tower!".
