It's not just the aura though, there are other abilities in play that target a single ally. Plus potentially targeting enemies as well. In addition, and I can't stress this enough, it's also every single turn, including the messy melee part of a fight. Asking a DM to know how many allies are within X aura, plus how many enemies are within X aura, plus how many allies and enemies are within X targeted distance every turn is a lot of tracking that normally isn't the case without a grid, and all that equals increased cognitive load on the DM.
And do you know who expects hyper accurate location information? Players do, especially when they have a whole mess of short range powers that require accurate distance information to a wide range of targets. It sounds like an enormous pain in the ass. Your comment about being picky isn't helpful either, because the model we have puts the entire onus on the DM to figure all this out. It would be a pain even if I weren't being picky, and I'm not a picky DM.
Why you can't take my reservations about this at face value baffles me. So I guess we're both baffled.
