Soaking tower shots is actually really important much of the time, and it essentially gives him an enormous amount of defensive stats no other Support could get with the same budget, so he can go where he's needed to peel for his team without worrying about being instantly deleted. It's "boring", sure, but it's a very effective ult.
But after that part where you have 0 abilities on u why should the enemy team fear you if you got no abilities left to bother them your just a walking sack of hp that they can take then ignore you afterwards heck they would let you back without killing you that's how non threatening a alistar is without any abilities. In other words I see no reason to focus or peel off alistar after his abilities are used.
