Why updated graphics matter
Everything from the spikes to the grip to the shape of the head, it's all more detailed and crisp on the newer model. The older model is a collection of polygonal shapes that bear only a vague resemblance to a hammer compared to the newer model, which is itself still not as good as models we have in the game now, never mind some of the Warlords drops we're about to see. The gap between these two hammers is the gap between 2004 and 2011, and here we are, three years later than that – and they show us how much a ten year old game can in fact change.
But if we're going back to MC for an anniversary, I want it to be a big deal – we should see those classic drops again, and we should see them with some visual flair added. The Brutality Blade, the Core Hound Tooth, the OEB, our old tier sets – I have no idea how feasible the idea of having these items drop in MC LFR is, with updated graphics and stats. I don't even know if we're getting any loot drops in the updated MC beyond the crowns for killing Ragnaros at the end.
And truth be told, it's not just MC that could use the update. We've seen a lot of effort put into character models getting their update, and frankly it was a good call on Blizzard's part. Updating those models was important. And yes, I'd always choose new content with new items over updating old stuff. But updating does more than let you just mog to it without shame – it helps preserve the visual set of the world, keeping all items looking like they are part of the same setting, the same milieu. The Sulfuras from Firelands doesn't look out of place wielded with armor from more recent raids, but the old one, legendary or not, just looks antiquated, a relic, not a weapon of legend.
Here's hoping we seem graphical updating remain a priority past the character models. Yes, new is good, but sometimes we need to put some effort into keeping things visually current.
