I did indeed end up tanking something with Dingle. We did a guild run of 10-man Naxx. An achievement run, to do The Dedicated Few, where you have to defeat most of the bosses (apart from the Four Horsemen) with only 8 people. Talk about trying to fly before you can walk.
All I can say is that our healers are awesome. And I only occasionally failed (such as a death to a soft-enraged Patchwerk), thanks to an equally awesome main tank (who kept me from looking foolish, especially on the AoE trash pulls). Of all the bosses, we only have Four Horsemen, Sapphiron and Kel’Thuzad left to clear; we called it after a single attempt at the Horsemen, as we need another couple of people (at least one more healer) for that (and it was ridiculously late, especially by NZ time).
But I managed to get not only two straight upgrades (new shoulders and leggings), but also a couple of items (another pair of shoulders and leggings) towards a DPS set that may possibly get some use when dual-specs go live. I crafted a set of frost-resist gear as well, for when we go back to Sapphiron, so I’m pretty much set for the rest of the run.
I think I need to start running heroics, though, if I want to get Dingle geared up any further; there’s only so many more Naxx runs left before we get Ulduar to explore, and there’s a few toys I can still pick up from heroics before then.
For now, though? Time for dailies.
