The reason you dont have CDs in vanilla is because its so ridiculously easy it's not needed. You have 10 year old f2p kids with pentium 2s from brazil facerolling naxx40 in classic Pservers with their 1 button fire mage rotation and warriors who literally just make a shield block/sunder/heroic strike 1 button macro.
lmao, let's wait and see how people fare in 40 man naxx again, I don't think any of the private servers have gotten that far yet in terms of patches released. If it was as easy as you seem to think, a lot more people would have cleared it back in the day. It was only out for like 7-8 months before BC came out which didn't give people in retail vanilla a lot of time for naxx, but still I doubt it's going to be very easy even these days when people get around to it again
also you still need CDs for "oh shit" moments, you just only get a few maximum and they have much longer cooldowns, like shield wall having a 30 min cooldown on prot warriors IIRC
The "best" players in the world in 2004/2005 were all clickers and keyboard turners, even the mage GM of nihilum was a clicker till he got exposed and humiliated, kungen was literally jumping around like an idiot spamming emotes and not seriously DPSing in their BWL clear videos. Average player now will faceroll any content now that they actually know how to keybind/move and the 1 mechanic of each fight has been done and studied to death.
Thats like saying computers were more complicated and required more skill 15-20 years ago, when the truth is the average person was just dumb as a rock and uninformed at the time.
Well like I said earlier, let's actually wait and see what happens when kids start doing this stuff again.
And do you know if those BWL vids were their first clears? If they already had it on farm then I wouldn't be surprised. ---
I may not go down in history, but I will go down on your sister.
