The Op has a point. If keycloning is getting banned because it falls under automatic usage, there is a valid question of what will be banned next.
Is info gathering addons allowed? You don’t manually press a button to get info from auctioneering addons, they scan the AH for you.
Rarescanners. Will they be banned as well? You don’t tab the area around you to find the rare mobs, the addon does it for you.
Quest helpers? Same here, you get an advantage compared to retail, gathering info reg. where to quest and what mobs to kill, allthou this one isn’t really that valid now since Blizzard them self has implemented a quest helping system.
DBM who scans bosses on what skills they use so you can avoid them. You don’t scan the boss yourself really. DBM tells you what is going on. And that feature is automated.
This list can go on forever really.
