It would seem like you took my post personally, for that I apologize.
However, while I didn't raid the newest content in MoP I keep up to date about it. And simply it's casual... I played enough MoP to know that, cleared SoO HC with some old friends (we levelled up started gearing and cleared it within 1 week) same story as it was during Cataclysm, where we cleared Dragonsoul without 1 piece of HC Firelands gear gear after 2 weeks(we started raiding / Gearing 2 weeks before Dragonsoul release). And continued to do so in HC. The story would be the same in the rest of MoP... The prior raids gave zero satisfaction, and let me tell you wether you believe me or not... It's 100% casual, the preparation you have to do before raiding is null and void compared to the old times. It's just not satisfying if you're an old-school hard core player.
You realize you needed several BiS geared BWL / AQ tanks to just do trash in Naxxramas.. Not to mention if they didn't have full consumables they'd just be 1 shot anyways... And full consumables in Vanilla was not buff food and flask... lol It was pots flasks, items, scrolls, elixirs random quirky things you could farm in the world etc.. Buff lines on a tank in vanilla was 30+ buffs, and Flask ontop of that..
In vanilla consumables such as flasks for tanks was 100% must even when in full T2 and farming BWL.
If you didn't bosses like Broodlord and Chrom would just 1 shot tanks. And a flask wasn't simply 10 min farming and you got it, a single flask farmed by 1 person if all herb nodes were up still took 60-70 minutes. Not to mention you had to be in Scholomance to make the flasks, at an alchemy table...
Twin emps, could hit a tank for a clean 10k hit.. (generally tank would be left with 300 hp after one of these if he was Decked out).
Naxx was harder, even trash could do that there.. It's simply something you can't talk about if you haven't experienced it.. Being a healer in Vanilla was A RUSH. Not like today's mindless spammfest. You had to manage mana at a superb level, Time heals avoid overhealing and make sure there was ALWAYS a heal in the air for the tank.. Doing so without spamming your brain out.
Using Pots, CD's, Felwood herbs, Demonic / Dark runes etc all to make sure you didn't run OOM. As priest, time heals to always have 1-2 seconds of while not casting regen etc was a must in certain fights.
Both in AQ and Naxx if you pulled trash and healers didn't already have heals in the air when the mobs reached the tank it was generally a wipe. The same if tanks didn't instantly get aggro from the one who pulled. Several trash packs required 3-4 tanks and CC targets. If CC was off, or if one of the tanks didn't pick his add the tank who then got this one would just die. It was extraordinary in the full extent of the word
Glorious if you will.
