Breakfast Topic: What will you miss most from the Wrath era?

This Breakfast Topic has been brought to you by Seed, the Aol guest writer program that brings your words to WoW Insider's pages.

I have to admit (although somewhat shamefacedly) that the only raid instance I saw before Wrath launched was Karazhan. Even worse, I was only watching my roommate running around this fantastic place, slaying beasts and praying (yes, he was actually praying) for the purples to come his way. At the time, I had abandoned my first toon, a level 23 orc warrior, and I had made amazing strides leveling my holy paladin to the grand status of level 61 before taking a break. As a result, I never raided when there were massive 40-man raids or when raiding was "hard," as those BC/vanilla veterans will say, so I can't say that I'll miss some of those raids that might disappear as Cataclysm reshapes the world as we know it. As for the zones getting hit hardest by Cataclysm, I can truthfully say I'm quite fond of bidding most of them farewell. Will anyone other than die-hard Chuck Norris fans really miss The Barrens?

So what is it about WoW that I will miss when the game changes for Cataclysm? It's the fast-paced content, the extreme value of a global cooldown. Many players stress at the thought of tanks getting killed in two to three hits from a raid boss, while I thrive on the risk. During our initial attempts at Festergut, the challenge of being able to time a ridiculously strong Holy Light in between swings from the abomination to keep the tanks alive was exhilarating. As a ret paladin in PVP, I love being jumped by a rogue in a battleground. If he couldn't kill me during his initial stun, I'd probably burst him down to nothing during mine. With the dramatically increase health pools and lower comparative healing/damage planned for Cataclysm, there won't be as many hair-trigger reactions needed to stay alive. I'm pretty sure I'm going to miss the current model, in which a single GCD no longer means life or death for someone in my raid.

When Cataclysm hits, most players will miss a specific zone or instance. What do you think you'll miss? A particular ability or general function? Or are you among those who think change is good, that paladins shouldn't have bubble/hearth and it's OK if mages can bloodlust?
