It isn't a matter of just utility vs survivability though. The AOE damage is an element of survival because killing mobs before they touch you is a part of that. I prefer Lightning Flash for Elite hunting but Thunderclap is probably equal or better when it comes to progressing Acts because it allows you to kill grunt groups faster and chase down problematic ones. Plus, constant movement allows for some additional dodging benefits, particularly against slow moving attacks like fireballs.
I'd say that covering distance for enemies is part of the utility aspect of it rather than survival, to be honest, but I suppose that's just me. That said, I try to minimize changing builds much so, to me, "Elite hunting" would basically be my target goal the majority of the time rather than dealing with trash that much. I mean, I do run Backlash so the extra Evasion does help with that so +Dodge% does help with that as well.
But, yeah, the teleport is nice for various enemies in Act 2 and 3 so it's not useless. I'd just argue that +Dodge% is better generally over it. That said, it's still down to these two runes for FoT primarily.
Also AOE = Lots of Life on Hit procs.
To be fair, Fist of Thunder itself has a small frontal-arc Area of Effect itself. But, yes, that's true as well.
