Just cause login issues have eased up somewhat now, doesn't mean they won't return. When a big patch or an expac comes out, there will probably be a rush to login again. And even if people AFK'ing weren't causing issues, it was a point of contention for the people who weren't able to login. If you are being told the world is full while your friends are saying there are a ton of zombies just staring at Aetheryte crystals around the world for hours, it is irritating.
Besides the few real flimsy reasons I see for people having "legit" reasons to want to AFK longer than 30 minutes are just that, flimsy. Not worth the angst not having the timer creates.
